You have successfully unbundled ARPACK and are now in the ARPACK directory that was created for you. 2. Recent bug fixes are included in patch.tar.gz and ppatch.tar.gz (only needed if you are using PARPACK also.) If you have not retrieved these files, please do so and place them in the directory right above the current directory. (They should be in the same directory where arpack96.tar reside). Use uncompress or gunzip to unzip the tar files, and use 'tar -xvf ' to unbundle these patches. The source codes in these patches will overwrite those contained in arpack96.tar and parpack96.tar. 3. Upon executing the 'ls | more ' command you should see BLAS DOCUMENTS EXAMPLES LAPACK README SRC UTIL Makefile ARmake.inc ARMAKES The following entries are directories: ARMAKES, BLAS, DOCUMENTS, EXAMPLES, LAPACK, SRC, UTIL The directory SRC contains the top level routines including the highest level reverse communication interface routines ssaupd, dsaupd - symmetric single and double precision snaupd, dnaupd - non-symmetric single and double precision cnaupd, cnaupd - complex non-symmetric single and double precision The headers of these routines contain full documentation of calling sequence and usage. Additional information is in the DOCUMENTS directory. 4. Example driver programs that illustrate all the computational modes, data types and precisions may be found in the EXAMPLES directory. Upon executing the 'ls EXAMPLES | more ' command you should see BAND COMPLEX NONSYM README SIMPLE SVD SYM Example programs for banded, complex, nonsymmetric, symmetric, and singular value decomposition may be found in the directories BAND, COMPLEX, NONSYM, SYM, SVD respectively. Look at the README file for further information. To get started, get into the SIMPLE directory to see example programs that illustrate the use of ARPACK in the simplest modes of operation for the most commonly posed standard eigenvalue problems. The following instructions explain how to make the ARPACK library. 5. Before you can compile anything, you must first edit and correct the file ARmake.inc. Sample ARmake.inc's can be found in the ARMAKES directory. Edit "ARmake.inc" and change the definition "home" to the root of the source tree (Top level of ARPACK directory) The makefile is set up to build a self-contained library which includes the needed BLAS 1/2/3 and LAPACK routines. If you already have the BLAS and LAPACK libraries installed on your system you might want to change the definition of DIRS as indicated in the ARmake.inc file. *** NOTE *** Unless the LAPACK library on your system is version 2.0, we strongly recommend that you install the LAPACK routines provided with ARPACK. Note that the current LAPACK release is version 3.0; if you are not sure which version of LAPACK is installed, pleaase compile and link to the subset of LAPACK included with ARPACK. 6. You will also need to change the file "second.f" in the UTIL directory to whatever is appropriate for timing on your system. The "second" routine provided works on most workstations. If you are running on a Cray, you can just edit the makefile in UTIL and take out the reference to "second.o" to use the system second routine. 7. Do "make lib" in the current directory to build the standard library "libarpack_$(PLAT).a" 8. Within DOCUMENTS directory there are three files ex-sym.doc ex-nonsym.doc and ex-complex.doc for templates on how to invoke the computational modes of ARPACK. Also look in the README file for explanations concerning the other documents.

This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

KAPPA in the Kahan's test for orthogonality is set to 0.717, the same as used by Gragg & Reichel. However computational experience indicates that this is a little too strict and will frequently force reorthogonalization when it is not necessary to do so. Also the "moving boundary" idea is not currently activated in the nonsymmetric code since it is not conclusive that it's the right thing to do all the time. Requires further investigation. As of 02/01/93 Richard Lehoucq assumes software control of the codes from Phuong Vu. On 03/01/93 all the *.F files were migrated SCCS. The 1.1 version of codes are those received from Phuong Vu. The frozen version of 07/08/92 is now considered version 1.1. Version 2.1 contains two new symmetric routines, sesrt and seupd. Changes as well as bug fixes for version 1.1 codes that were only corrected for programming bugs are version 1.2. These 1.2 versions will also be in version 2.1. Subroutine [d,s]saupd now requires slightly more workspace. See [d,s]saupd for the details. \SCCS Information: @(#) FILE: version.h SID: 2.3 DATE OF SID: 11/16/95 RELEASE: 2 */ #define VERSION_NUMBER ' 2.1' #define VERSION_DATE ' 11/15/95' arpack-0.90/SRC/sgetv0.f0000644000175000017500000003146610772511052011644 00000000000000c----------------------------------------------------------------------- c\BeginDoc c c\Name: sgetv0 c c\Description: c Generate a random initial residual vector for the Arnoldi process. c Force the residual vector to be in the range of the operator OP. c c\Usage: c call sgetv0 c ( IDO, BMAT, ITRY, INITV, N, J, V, LDV, RESID, RNORM, c IPNTR, WORKD, IERR ) c c\Arguments c IDO Integer.

(INPUT/OUTPUT) c On entry, the upper Hessenberg matrix H. c On exit, if WANTT is .TRUE., H is upper quasi-triangular in c rows and columns ILO:IHI, with any 2-by-2 diagonal blocks in c standard form. If WANTT is .FALSE., the contents of H are c unspecified on exit. c c LDH Integer. (INPUT) c The leading dimension of the array H. LDH >= max(1,N). c c WR Real array, dimension (N). (OUTPUT) c WI Real array, dimension (N). (OUTPUT) c The real and imaginary parts, respectively, of the computed c eigenvalues ILO to IHI are stored in the corresponding c elements of WR and WI. If two eigenvalues are computed as a c complex conjugate pair, they are stored in consecutive c elements of WR and WI, say the i-th and (i+1)th, with c WI(i) > 0 and WI(i+1) < 0. If WANTT is .TRUE., the c eigenvalues are stored in the same order as on the diagonal c of the Schur form returned in H, with WR(i) = H(i,i), and, if c H(i:i+1,i:i+1) is a 2-by-2 diagonal block, c WI(i) = sqrt(H(i+1,i)*H(i,i+1)) and WI(i+1) = -WI(i). c c Z Real array, dimension (N). (OUTPUT) c On exit Z contains the last components of the Schur vectors. c c INFO Integer. (OUPUT) c = 0: successful exit c > 0: SLAQRB failed to compute all the eigenvalues ILO to IHI c in a total of 30*(IHI-ILO+1) iterations; if INFO = i, c elements i+1:ihi of WR and WI contain those eigenvalues c which have been successfully computed. c c\Remarks c 1.

(INPUT/OUTPUT) c Contains the number of implicit shifts to apply during c each Arnoldi iteration. c If ISHIFT=1, NP is adjusted dynamically at each iteration c to accelerate convergence and prevent stagnation. c This is also roughly equal to the number of matrix-vector c products (involving the operator OP) per Arnoldi iteration. c The logic for adjusting is contained within the current c subroutine. c If ISHIFT=0, NP is the number of shifts the user needs c to provide via reverse comunication. 0 < NP < NCV-NEV. c NP may be less than NCV-NEV for two reasons. The first, is c to keep complex conjugate pairs of "wanted" Ritz values c together. The second, is that a leading block of the current c upper Hessenberg matrix has split off and contains "unwanted" c Ritz values. c Upon termination of the IRA iteration, NP contains the number c of "converged" wanted Ritz values. c c IUPD Integer. (INPUT) c IUPD .EQ. 0: use explicit restart instead implicit update. c IUPD .NE. 0: use implicit update. c c V Real N by (NEV+NP) array. (INPUT/OUTPUT) c The Arnoldi basis vectors are returned in the first NEV c columns of V. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling c program. c c H Real (NEV+NP) by (NEV+NP) array. (OUTPUT) c H is used to store the generated upper Hessenberg matrix c c LDH Integer. (INPUT) c Leading dimension of H exactly as declared in the calling c program. c c RITZR, Real arrays of length NEV+NP. (OUTPUT) c RITZI RITZR(1:NEV) (resp. RITZI(1:NEV)) contains the real (resp. c imaginary) part of the computed Ritz values of OP. c c BOUNDS Real array of length NEV+NP. (OUTPUT) c BOUNDS(1:NEV) contain the error bounds corresponding to c the computed Ritz values. c c Q Real (NEV+NP) by (NEV+NP) array. (WORKSPACE) c Private (replicated) work array used to accumulate the c rotation in the shift application step. c c LDQ Integer. (INPUT) c Leading dimension of Q exactly as declared in the calling c program. c c WORKL Real work array of length at least c (NEV+NP)**2 + 3*(NEV+NP). (INPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. It is used in shifts calculation, shifts c application and convergence checking. c c On exit, the last 3*(NEV+NP) locations of WORKL contain c the Ritz values (real,imaginary) and associated Ritz c estimates of the current Hessenberg matrix. They are c listed in the same order as returned from sneigh. c c If ISHIFT .EQ. O and IDO .EQ. 3, the first 2*NP locations c of WORKL are used in reverse communication to hold the user c supplied shifts. c c IPNTR Integer array of length 3. (OUTPUT) c Pointer to mark the starting locations in the WORKD for c vectors used by the Arnoldi iteration. c ------------------------------------------------------------- c IPNTR(1): pointer to the current operand vector X. c IPNTR(2): pointer to the current result vector Y. c IPNTR(3): pointer to the vector B * X when used in the c shift-and-invert mode.

(WORKSPACE) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration !!!!!!!!!! c See Data Distribution Note in DNAUPD. c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal return. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. c NP returns the number of converged Ritz values. c = 2: No shifts could be applied. c = -8: Error return from LAPACK eigenvalue calculation; c This should never happen. c = -9: Starting vector is zero. c = -9999: Could not build an Arnoldi factorization. c Size that was built in returned in NP. c c\EndDoc c c----------------------------------------------------------------------- c c\BeginLib c c\Local variables: c xxxxxx real c c\References: c 1.

This subroutine computes approximations to a few eigenpairs c of a linear operator "OP" with respect to a semi-inner product defined by c a symmetric positive semi-definite real matrix B. B may be the identity c matrix. NOTE: If the linear operator "OP" is real and symmetric c with respect to the real positive semi-definite symmetric matrix B, c i.e. B*OP = (OP`)*B, then subroutine ssaupd should be used instead. c c The computed approximate eigenvalues are called Ritz values and c the corresponding approximate eigenvectors are called Ritz vectors. c c snaupd is usually called iteratively to solve one of the c following problems: c c Mode 1: A*x = lambda*x. c ===> OP = A and B = I. c c Mode 2: A*x = lambda*M*x, M symmetric positive definite c ===> OP = inv[M]*A and B = M. c ===> (If M can be factored see remark 3 below) c c Mode 3: A*x = lambda*M*x, M symmetric semi-definite c ===> OP = Real_Part{ inv[A - sigma*M]*M } and B = M. c ===> shift-and-invert mode (in real arithmetic) c If OP*x = amu*x, then c amu = 1/2 * [ 1/(lambda-sigma) + 1/(lambda-conjg(sigma)) ]. c Note: If sigma is real, i.e. imaginary part of sigma is zero; c Real_Part{ inv[A - sigma*M]*M } == inv[A - sigma*M]*M c amu == 1/(lambda-sigma). c c Mode 4: A*x = lambda*M*x, M symmetric semi-definite c ===> OP = Imaginary_Part{ inv[A - sigma*M]*M } and B = M. c ===> shift-and-invert mode (in real arithmetic) c If OP*x = amu*x, then c amu = 1/2i * [ 1/(lambda-sigma) - 1/(lambda-conjg(sigma)) ]. c c Both mode 3 and 4 give the same enhancement to eigenvalues close to c the (complex) shift sigma. However, as lambda goes to infinity, c the operator OP in mode 4 dampens the eigenvalues more strongly than c does OP defined in mode 3. c c NOTE: The action of w <- inv[A - sigma*M]*v or w <- inv[M]*v c should be accomplished either by a direct method c using a sparse matrix factorization and solving c c [A - sigma*M]*w = v or M*w = v, c c or through an iterative method for solving these c systems. If an iterative method is used, the c convergence test must be more stringent than c the accuracy requirements for the eigenvalue c approximations. c c\Usage: c call snaupd c ( IDO, BMAT, N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, c IPNTR, WORKD, WORKL, LWORKL, INFO ) c c\Arguments c IDO Integer. (INPUT/OUTPUT) c Reverse communication flag. IDO must be zero on the first c call to snaupd. IDO will be set internally to c indicate the type of operation to be performed. Control is c then given back to the calling routine which has the c responsibility to carry out the requested operation and call c snaupd with the result. The operand is given in c WORKD(IPNTR(1)), the result must be put in WORKD(IPNTR(2)). c ------------------------------------------------------------- c IDO = 0: first call to the reverse communication interface c IDO = -1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c This is for the initialization phase to force the c starting vector into the range of OP. c IDO = 1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c In mode 3 and 4, the vector B * X is already c available in WORKD(ipntr(3)). It does not c need to be recomputed in forming OP * X. c IDO = 2: compute Y = B * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c IDO = 3: compute the IPARAM(8) real and imaginary parts c of the shifts where INPTR(14) is the pointer c into WORKL for placing the shifts. See Remark c 5 below. c IDO = 99: done c ------------------------------------------------------------- c c BMAT Character*1. (INPUT) c BMAT specifies the type of the matrix B that defines the c semi-inner product for the operator OP. c BMAT = 'I' -> standard eigenvalue problem A*x = lambda*x c BMAT = 'G' -> generalized eigenvalue problem A*x = lambda*B*x c c N Integer. (INPUT) c Dimension of the eigenproblem. c c WHICH Character*2. (INPUT) c 'LM' -> want the NEV eigenvalues of largest magnitude. c 'SM' -> want the NEV eigenvalues of smallest magnitude. c 'LR' -> want the NEV eigenvalues of largest real part. c 'SR' -> want the NEV eigenvalues of smallest real part. c 'LI' -> want the NEV eigenvalues of largest imaginary part. c 'SI' -> want the NEV eigenvalues of smallest imaginary part. c c NEV Integer. (INPUT/OUTPUT) c Number of eigenvalues of OP to be computed. 0 < NEV < N-1. c c TOL Real scalar. (INPUT) c Stopping criterion: the relative accuracy of the Ritz value c is considered acceptable if BOUNDS(I) .LE. TOL*ABS(RITZ(I)) c where ABS(RITZ(I)) is the magnitude when RITZ(I) is complex. c DEFAULT = SLAMCH('EPS') (machine precision as computed c by the LAPACK auxiliary subroutine SLAMCH). c c RESID Real array of length N. (INPUT/OUTPUT) c On INPUT: c If INFO .EQ. 0, a random initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c On OUTPUT: c RESID contains the final residual vector. c c NCV Integer. (INPUT) c Number of columns of the matrix V. NCV must satisfy the two c inequalities 2 <= NCV-NEV and NCV <= N. c This will indicate how many Arnoldi vectors are generated c at each iteration. After the startup phase in which NEV c Arnoldi vectors are generated, the algorithm generates c approximately NCV-NEV Arnoldi vectors at each subsequent update c iteration. Most of the cost in generating each Arnoldi vector is c in the matrix-vector operation OP*x. c NOTE: 2 <= NCV-NEV in order that complex conjugate pairs of Ritz c values are kept together. (See remark 4 below) c c V Real array N by NCV. (OUTPUT) c Contains the final set of Arnoldi basis vectors. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling program. c c IPARAM Integer array of length 11. (INPUT/OUTPUT) c IPARAM(1) = ISHIFT: method for selecting the implicit shifts. c The shifts selected at each iteration are used to restart c the Arnoldi iteration in an implicit fashion. c ------------------------------------------------------------- c ISHIFT = 0: the shifts are provided by the user via c reverse communication. The real and imaginary c parts of the NCV eigenvalues of the Hessenberg c matrix H are returned in the part of the WORKL c array corresponding to RITZR and RITZI. See remark c 5 below. c ISHIFT = 1: exact shifts with respect to the current c Hessenberg matrix H. This is equivalent to c restarting the iteration with a starting vector c that is a linear combination of approximate Schur c vectors associated with the "wanted" Ritz values. c ------------------------------------------------------------- c c IPARAM(2) = No longer referenced. c c IPARAM(3) = MXITER c On INPUT: maximum number of Arnoldi update iterations allowed. c On OUTPUT: actual number of Arnoldi update iterations taken. c c IPARAM(4) = NB: blocksize to be used in the recurrence. c The code currently works only for NB = 1. c c IPARAM(5) = NCONV: number of "converged" Ritz values. c This represents the number of Ritz values that satisfy c the convergence criterion. c c IPARAM(6) = IUPD c No longer referenced. Implicit restarting is ALWAYS used. c c IPARAM(7) = MODE c On INPUT determines what type of eigenproblem is being solved. c Must be 1,2,3,4; See under \Description of snaupd for the c four modes available. c c IPARAM(8) = NP c When ido = 3 and the user provides shifts through reverse c communication (IPARAM(1)=0), snaupd returns NP, the number c of shifts the user is to provide. 0 < NP <=NCV-NEV. See Remark c 5 below. c c IPARAM(9) = NUMOP, IPARAM(10) = NUMOPB, IPARAM(11) = NUMREO, c OUTPUT: NUMOP = total number of OP*x operations, c NUMOPB = total number of B*x operations if BMAT='G', c NUMREO = total number of steps of re-orthogonalization. c c IPNTR Integer array of length 14. (OUTPUT) c Pointer to mark the starting locations in the WORKD and WORKL c arrays for matrices/vectors used by the Arnoldi iteration. c ------------------------------------------------------------- c IPNTR(1): pointer to the current operand vector X in WORKD. c IPNTR(2): pointer to the current result vector Y in WORKD. c IPNTR(3): pointer to the vector B * X in WORKD when used in c the shift-and-invert mode. c IPNTR(4): pointer to the next available location in WORKL c that is untouched by the program. c IPNTR(5): pointer to the NCV by NCV upper Hessenberg matrix c H in WORKL. c IPNTR(6): pointer to the real part of the ritz value array c RITZR in WORKL. c IPNTR(7): pointer to the imaginary part of the ritz value array c RITZI in WORKL. c IPNTR(8): pointer to the Ritz estimates in array WORKL associated c with the Ritz values located in RITZR and RITZI in WORKL. c c IPNTR(14): pointer to the NP shifts in WORKL. See Remark 5 below. c c Note: IPNTR(9:13) is only referenced by sneupd.

Only referenced by c sneupd if RVEC = .TRUE. See Remark 2 below. c ------------------------------------------------------------- c c WORKD Real work array of length 3*N. (REVERSE COMMUNICATION) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration. Upon termination c WORKD(1:N) contains B*RESID(1:N). If an invariant subspace c associated with the converged Ritz values is desired, see remark c 2 below, subroutine sneupd uses this output. c See Data Distribution Note below. c c WORKL Real work array of length LWORKL. (OUTPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. See Data Distribution Note below. c c LWORKL Integer. (INPUT) c LWORKL must be at least 3*NCV**2 + 6*NCV. c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal exit. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. IPARAM(5) c returns the number of wanted converged Ritz values. c = 2: No longer an informational error. Deprecated starting c with release 2 of ARPACK. c = 3: No shifts could be applied during a cycle of the c Implicitly restarted Arnoldi iteration. One possibility c is to increase the size of NCV relative to NEV. c See remark 4 below. c = -1: N must be positive. c = -2: NEV must be positive. c = -3: NCV-NEV >= 2 and less than or equal to N. c = -4: The maximum number of Arnoldi update iteration c must be greater than zero. c = -5: WHICH must be one of 'LM', 'SM', 'LR', 'SR', 'LI', 'SI' c = -6: BMAT must be one of 'I' or 'G'. c = -7: Length of private work array is not sufficient. c = -8: Error return from LAPACK eigenvalue calculation; c = -9: Starting vector is zero. c = -10: IPARAM(7) must be 1,2,3,4. c = -11: IPARAM(7) = 1 and BMAT = 'G' are incompatable. c = -12: IPARAM(1) must be equal to 0 or 1. c = -9999: Could not build an Arnoldi factorization. c IPARAM(5) returns the size of the current Arnoldi c factorization. c c\Remarks c 1. The computed Ritz values are approximate eigenvalues of OP. The c selection of WHICH should be made with this in mind when c Mode = 3 and 4. After convergence, approximate eigenvalues of the c original problem may be obtained with the ARPACK subroutine sneupd. c c 2. If a basis for the invariant subspace corresponding to the converged Ritz c values is needed, the user must call sneupd immediately following c completion of snaupd. This is new starting with release 2 of ARPACK. c c 3. If M can be factored into a Cholesky factorization M = LL` c then Mode = 2 should not be selected. Instead one should use c Mode = 1 with OP = inv(L)*A*inv(L`). Appropriate triangular c linear systems should be solved with L and L` rather c than computing inverses. After convergence, an approximate c eigenvector z of the original problem is recovered by solving c L`z = x where x is a Ritz vector of OP. c c 4. At present there is no a-priori analysis to guide the selection c of NCV relative to NEV. The only formal requrement is that NCV > NEV + 2. c However, it is recommended that NCV .ge. 2*NEV+1. If many problems of c the same type are to be solved, one should experiment with increasing c NCV while keeping NEV fixed for a given test problem. This will c usually decrease the required number of OP*x operations but it c also increases the work and storage required to maintain the orthogonal c basis vectors. The optimal "cross-over" with respect to CPU time c is problem dependent and must be determined empirically. c See Chapter 8 of Reference 2 for further information. c c 5.

For symmetric problems this reduces to a variant of the Lanczos c method. This method has been designed to compute approximations to a c few eigenpairs of a linear operator OP that is real and symmetric c with respect to a real positive semi-definite symmetric matrix B, c i.e. c c B*OP = (OP`)*B. c c Another way to express this condition is c c < x,OPy > = < OPx,y > where < z,w > = z`Bw . c c In the standard eigenproblem B is the identity matrix. c ( A` denotes transpose of A) c c The computed approximate eigenvalues are called Ritz values and c the corresponding approximate eigenvectors are called Ritz vectors. c c ssaupd is usually called iteratively to solve one of the c following problems: c c Mode 1: A*x = lambda*x, A symmetric c ===> OP = A and B = I. c c Mode 2: A*x = lambda*M*x, A symmetric, M symmetric positive definite c ===> OP = inv[M]*A and B = M. c ===> (If M can be factored see remark 3 below) c c Mode 3: K*x = lambda*M*x, K symmetric, M symmetric positive semi-definite c ===> OP = (inv[K - sigma*M])*M and B = M. c ===> Shift-and-Invert mode c c Mode 4: K*x = lambda*KG*x, K symmetric positive semi-definite, c KG symmetric indefinite c ===> OP = (inv[K - sigma*KG])*K and B = K. c ===> Buckling mode c c Mode 5: A*x = lambda*M*x, A symmetric, M symmetric positive semi-definite c ===> OP = inv[A - sigma*M]*[A + sigma*M] and B = M. c ===> Cayley transformed mode c c NOTE: The action of w <- inv[A - sigma*M]*v or w <- inv[M]*v c should be accomplished either by a direct method c using a sparse matrix factorization and solving c c [A - sigma*M]*w = v or M*w = v, c c or through an iterative method for solving these c systems. If an iterative method is used, the c convergence test must be more stringent than c the accuracy requirements for the eigenvalue c approximations. c c\Usage: c call ssaupd c ( IDO, BMAT, N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, c IPNTR, WORKD, WORKL, LWORKL, INFO ) c c\Arguments c IDO Integer. (INPUT/OUTPUT) c Reverse communication flag. IDO must be zero on the first c call to ssaupd. IDO will be set internally to c indicate the type of operation to be performed. Control is c then given back to the calling routine which has the c responsibility to carry out the requested operation and call c ssaupd with the result. The operand is given in c WORKD(IPNTR(1)), the result must be put in WORKD(IPNTR(2)). c (If Mode = 2 see remark 5 below) c ------------------------------------------------------------- c IDO = 0: first call to the reverse communication interface c IDO = -1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c This is for the initialization phase to force the c starting vector into the range of OP. c IDO = 1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c In mode 3,4 and 5, the vector B * X is already c available in WORKD(ipntr(3)). It does not c need to be recomputed in forming OP * X. c IDO = 2: compute Y = B * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c IDO = 3: compute the IPARAM(8) shifts where c IPNTR(11) is the pointer into WORKL for c placing the shifts. See remark 6 below. c IDO = 99: done c ------------------------------------------------------------- c c BMAT Character*1. (INPUT) c BMAT specifies the type of the matrix B that defines the c semi-inner product for the operator OP. c B = 'I' -> standard eigenvalue problem A*x = lambda*x c B = 'G' -> generalized eigenvalue problem A*x = lambda*B*x c c N Integer. (INPUT) c Dimension of the eigenproblem. c c WHICH Character*2. (INPUT) c Specify which of the Ritz values of OP to compute. c c 'LA' - compute the NEV largest (algebraic) eigenvalues. c 'SA' - compute the NEV smallest (algebraic) eigenvalues. c 'LM' - compute the NEV largest (in magnitude) eigenvalues. c 'SM' - compute the NEV smallest (in magnitude) eigenvalues. c 'BE' - compute NEV eigenvalues, half from each end of the c spectrum. When NEV is odd, compute one more from the c high end than from the low end. c (see remark 1 below) c c NEV Integer. (INPUT) c Number of eigenvalues of OP to be computed. 0 < NEV < N. c c TOL Real scalar. (INPUT) c Stopping criterion: the relative accuracy of the Ritz value c is considered acceptable if BOUNDS(I) .LE. TOL*ABS(RITZ(I)). c If TOL .LE. 0. is passed a default is set: c DEFAULT = SLAMCH('EPS') (machine precision as computed c by the LAPACK auxiliary subroutine SLAMCH). c c RESID Real array of length N. (INPUT/OUTPUT) c On INPUT: c If INFO .EQ. 0, a random initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c On OUTPUT: c RESID contains the final residual vector. c c NCV Integer. (INPUT) c Number of columns of the matrix V (less than or equal to N). c This will indicate how many Lanczos vectors are generated c at each iteration. After the startup phase in which NEV c Lanczos vectors are generated, the algorithm generates c NCV-NEV Lanczos vectors at each subsequent update iteration. c Most of the cost in generating each Lanczos vector is in the c matrix-vector product OP*x. (See remark 4 below). c c V Real N by NCV array. (OUTPUT) c The NCV columns of V contain the Lanczos basis vectors. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling c program. c c IPARAM Integer array of length 11. (INPUT/OUTPUT) c IPARAM(1) = ISHIFT: method for selecting the implicit shifts. c The shifts selected at each iteration are used to restart c the Arnoldi iteration in an implicit fashion. c ------------------------------------------------------------- c ISHIFT = 0: the shifts are provided by the user via c reverse communication. The NCV eigenvalues of c the current tridiagonal matrix T are returned in c the part of WORKL array corresponding to RITZ. c See remark 6 below. c ISHIFT = 1: exact shifts with respect to the reduced c tridiagonal matrix T. This is equivalent to c restarting the iteration with a starting vector c that is a linear combination of Ritz vectors c associated with the "wanted" Ritz values. c ------------------------------------------------------------- c c IPARAM(2) = LEVEC c No longer referenced. See remark 2 below. c c IPARAM(3) = MXITER c On INPUT: maximum number of Arnoldi update iterations allowed. c On OUTPUT: actual number of Arnoldi update iterations taken. c c IPARAM(4) = NB: blocksize to be used in the recurrence. c The code currently works only for NB = 1. c c IPARAM(5) = NCONV: number of "converged" Ritz values. c This represents the number of Ritz values that satisfy c the convergence criterion. c c IPARAM(6) = IUPD c No longer referenced. Implicit restarting is ALWAYS used. c c IPARAM(7) = MODE c On INPUT determines what type of eigenproblem is being solved. c Must be 1,2,3,4,5; See under \Description of ssaupd for the c five modes available. c c IPARAM(8) = NP c When ido = 3 and the user provides shifts through reverse c communication (IPARAM(1)=0), ssaupd returns NP, the number c of shifts the user is to provide. 0 < NP <=NCV-NEV. See Remark c 6 below. c c IPARAM(9) = NUMOP, IPARAM(10) = NUMOPB, IPARAM(11) = NUMREO, c OUTPUT: NUMOP = total number of OP*x operations, c NUMOPB = total number of B*x operations if BMAT='G', c NUMREO = total number of steps of re-orthogonalization. c c IPNTR Integer array of length 11.

See Remark 6 below. c c Note: IPNTR(8:10) is only referenced by sseupd. See Remark 2. c IPNTR(8): pointer to the NCV RITZ values of the original system. c IPNTR(9): pointer to the NCV corresponding error bounds. c IPNTR(10): pointer to the NCV by NCV matrix of eigenvectors c of the tridiagonal matrix T. Only referenced by c sseupd if RVEC = .TRUE. See Remarks. c ------------------------------------------------------------- c c WORKD Real work array of length 3*N. (REVERSE COMMUNICATION) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration. Upon termination c WORKD(1:N) contains B*RESID(1:N). If the Ritz vectors are desired c subroutine sseupd uses this output. c See Data Distribution Note below. c c WORKL Real work array of length LWORKL. (OUTPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. See Data Distribution Note below. c c LWORKL Integer. (INPUT) c LWORKL must be at least NCV**2 + 8*NCV . c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal exit. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. IPARAM(5) c returns the number of wanted converged Ritz values. c = 2: No longer an informational error. Deprecated starting c with release 2 of ARPACK. c = 3: No shifts could be applied during a cycle of the c Implicitly restarted Arnoldi iteration. One possibility c is to increase the size of NCV relative to NEV. c See remark 4 below. c = -1: N must be positive. c = -2: NEV must be positive. c = -3: NCV must be greater than NEV and less than or equal to N. c = -4: The maximum number of Arnoldi update iterations allowed c must be greater than zero. c = -5: WHICH must be one of 'LM', 'SM', 'LA', 'SA' or 'BE'. c = -6: BMAT must be one of 'I' or 'G'. c = -7: Length of private work array WORKL is not sufficient. c = -8: Error return from trid. eigenvalue calculation; c Informatinal error from LAPACK routine ssteqr. c = -9: Starting vector is zero. c = -10: IPARAM(7) must be 1,2,3,4,5. c = -11: IPARAM(7) = 1 and BMAT = 'G' are incompatable. c = -12: IPARAM(1) must be equal to 0 or 1. c = -13: NEV and WHICH = 'BE' are incompatable. c = -9999: Could not build an Arnoldi factorization. c IPARAM(5) returns the size of the current Arnoldi c factorization. The user is advised to check that c enough workspace and array storage has been allocated. c c c\Remarks c 1. The converged Ritz values are always returned in ascending c algebraic order. The computed Ritz values are approximate c eigenvalues of OP. The selection of WHICH should be made c with this in mind when Mode = 3,4,5. After convergence, c approximate eigenvalues of the original problem may be obtained c with the ARPACK subroutine sseupd. c c 2. If the Ritz vectors corresponding to the converged Ritz values c are needed, the user must call sseupd immediately following completion c of ssaupd. This is new starting with version 2.1 of ARPACK. c c 3. If M can be factored into a Cholesky factorization M = LL` c then Mode = 2 should not be selected. Instead one should use c Mode = 1 with OP = inv(L)*A*inv(L`). Appropriate triangular c linear systems should be solved with L and L` rather c than computing inverses. After convergence, an approximate c eigenvector z of the original problem is recovered by solving c L`z = x where x is a Ritz vector of OP. c c 4. At present there is no a-priori analysis to guide the selection c of NCV relative to NEV. The only formal requrement is that NCV > NEV. c However, it is recommended that NCV .ge. 2*NEV. If many problems of c the same type are to be solved, one should experiment with increasing c NCV while keeping NEV fixed for a given test problem. This will c usually decrease the required number of OP*x operations but it c also increases the work and storage required to maintain the orthogonal c basis vectors. The optimal "cross-over" with respect to CPU time c is problem dependent and must be determined empirically. c c 5. If IPARAM(7) = 2 then in the Reverse commuication interface the user c must do the following. When IDO = 1, Y = OP * X is to be computed. c When IPARAM(7) = 2 OP = inv(B)*A. After computing A*X the user c must overwrite X with A*X. Y is then the solution to the linear set c of equations B*Y = A*X. c c 6. When IPARAM(1) = 0, and IDO = 3, the user needs to provide the c NP = IPARAM(8) shifts in locations: c 1 WORKL(IPNTR(11)) c 2 WORKL(IPNTR(11)+1) c . c . c . c NP WORKL(IPNTR(11)+NP-1). c c The eigenvalues of the current tridiagonal matrix are located in c WORKL(IPNTR(6)) through WORKL(IPNTR(6)+NCV-1). They are in the c order defined by WHICH. The associated Ritz estimates are located in c WORKL(IPNTR(8)), WORKL(IPNTR(8)+1), ... , WORKL(IPNTR(8)+NCV-1). c c----------------------------------------------------------------------- c c\Data Distribution Note: c c Fortran-D syntax: c ================ c REAL RESID(N), V(LDV,NCV), WORKD(3*N), WORKL(LWORKL) c DECOMPOSE D1(N), D2(N,NCV) c ALIGN RESID(I) with D1(I) c ALIGN V(I,J) with D2(I,J) c ALIGN WORKD(I) with D1(I) range (1:N) c ALIGN WORKD(I) with D1(I-N) range (N+1:2*N) c ALIGN WORKD(I) with D1(I-2*N) range (2*N+1:3*N) c DISTRIBUTE D1(BLOCK), D2(BLOCK,:) c REPLICATED WORKL(LWORKL) c c Cray MPP syntax: c =============== c REAL RESID(N), V(LDV,NCV), WORKD(N,3), WORKL(LWORKL) c SHARED RESID(BLOCK), V(BLOCK,:), WORKD(BLOCK,:) c REPLICATED WORKL(LWORKL) c c c\BeginLib c c\References: c 1.

An orthonormal c basis is always computed. There is an additional storage cost of n*nev c if both are requested (in this case a separate array Z must be supplied). c c The approximate eigenvalues and eigenvectors of A*z = lambda*B*z c are derived from approximate eigenvalues and eigenvectors of c of the linear operator OP prescribed by the MODE selection in the c call to SNAUPD. SNAUPD must be called before this routine is called. c These approximate eigenvalues and vectors are commonly called Ritz c values and Ritz vectors respectively. They are referred to as such c in the comments that follow. The computed orthonormal basis for the c invariant subspace corresponding to these Ritz values is referred to as a c Schur basis. c c See documentation in the header of the subroutine SNAUPD for c definition of OP as well as other terms and the relation of computed c Ritz values and Ritz vectors of OP with respect to the given problem c A*z = lambda*B*z. For a brief description, see definitions of c IPARAM(7), MODE and WHICH in the documentation of SNAUPD. c c\Usage: c call sneupd c ( RVEC, HOWMNY, SELECT, DR, DI, Z, LDZ, SIGMAR, SIGMAI, WORKEV, BMAT, c N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, IPNTR, WORKD, WORKL, c LWORKL, INFO ) c c\Arguments: c RVEC LOGICAL (INPUT) c Specifies whether a basis for the invariant subspace corresponding c to the converged Ritz value approximations for the eigenproblem c A*z = lambda*B*z is computed. c c RVEC = .FALSE. Compute Ritz values only. c c RVEC = .TRUE. Compute the Ritz vectors or Schur vectors. c See Remarks below. c c HOWMNY Character*1 (INPUT) c Specifies the form of the basis for the invariant subspace c corresponding to the converged Ritz values that is to be computed. c c = 'A': Compute NEV Ritz vectors; c = 'P': Compute NEV Schur vectors; c = 'S': compute some of the Ritz vectors, specified c by the logical array SELECT. c c SELECT Logical array of dimension NCV. (INPUT) c If HOWMNY = 'S', SELECT specifies the Ritz vectors to be c computed. To select the Ritz vector corresponding to a c Ritz value (DR(j), DI(j)), SELECT(j) must be set to .TRUE.. c If HOWMNY = 'A' or 'P', SELECT is used as internal workspace. c c DR Real array of dimension NEV+1. (OUTPUT) c If IPARAM(7) = 1,2 or 3 and SIGMAI=0.0 then on exit: DR contains c the real part of the Ritz approximations to the eigenvalues of c A*z = lambda*B*z. c If IPARAM(7) = 3, 4 and SIGMAI is not equal to zero, then on exit: c DR contains the real part of the Ritz values of OP computed by c SNAUPD. A further computation must be performed by the user c to transform the Ritz values computed for OP by SNAUPD to those c of the original system A*z = lambda*B*z. See remark 3 below. c c DI Real array of dimension NEV+1. (OUTPUT) c On exit, DI contains the imaginary part of the Ritz value c approximations to the eigenvalues of A*z = lambda*B*z associated c with DR. c c NOTE: When Ritz values are complex, they will come in complex c conjugate pairs. If eigenvectors are requested, the c corresponding Ritz vectors will also come in conjugate c pairs and the real and imaginary parts of these are c represented in two consecutive columns of the array Z c (see below). c c Z Real N by NEV+1 array if RVEC = .TRUE. and HOWMNY = 'A'. (OUTPUT) c On exit, if RVEC = .TRUE. and HOWMNY = 'A', then the columns of c Z represent approximate eigenvectors (Ritz vectors) corresponding c to the NCONV=IPARAM(5) Ritz values for eigensystem c A*z = lambda*B*z. c c The complex Ritz vector associated with the Ritz value c with positive imaginary part is stored in two consecutive c columns. The first column holds the real part of the Ritz c vector and the second column holds the imaginary part. The c Ritz vector associated with the Ritz value with negative c imaginary part is simply the complex conjugate of the Ritz vector c associated with the positive imaginary part. c c If RVEC = .FALSE. or HOWMNY = 'P', then Z is not referenced. c c NOTE: If if RVEC = .TRUE. and a Schur basis is not required, c the array Z may be set equal to first NEV+1 columns of the Arnoldi c basis array V computed by SNAUPD. In this case the Arnoldi basis c will be destroyed and overwritten with the eigenvector basis. c c LDZ Integer. (INPUT) c The leading dimension of the array Z. If Ritz vectors are c desired, then LDZ >= max( 1, N ). In any case, LDZ >= 1. c c SIGMAR Real (INPUT) c If IPARAM(7) = 3 or 4, represents the real part of the shift. c Not referenced if IPARAM(7) = 1 or 2. c c SIGMAI Real (INPUT) c If IPARAM(7) = 3 or 4, represents the imaginary part of the shift. c Not referenced if IPARAM(7) = 1 or 2.

These arguments MUST NOT BE MODIFIED between c the the last call to SNAUPD and the call to SNEUPD. c c Three of these parameters (V, WORKL, INFO) are also output parameters: c c V Real N by NCV array. (INPUT/OUTPUT) c c Upon INPUT: the NCV columns of V contain the Arnoldi basis c vectors for OP as constructed by SNAUPD . c c Upon OUTPUT: If RVEC = .TRUE. the first NCONV=IPARAM(5) columns c contain approximate Schur vectors that span the c desired invariant subspace. See Remark 2 below. c c NOTE: If the array Z has been set equal to first NEV+1 columns c of the array V and RVEC=.TRUE. and HOWMNY= 'A', then the c Arnoldi basis held by V has been overwritten by the desired c Ritz vectors. If a separate array Z has been passed then c the first NCONV=IPARAM(5) columns of V will contain approximate c Schur vectors that span the desired invariant subspace. c c WORKL Real work array of length LWORKL.

Currently only HOWMNY = 'A' and 'P' are implemented. c c Let trans(X) denote the transpose of X. c c 2. Schur vectors are an orthogonal representation for the basis of c Ritz vectors. Thus, their numerical properties are often superior. c If RVEC = .TRUE. then the relationship c A * V(:,1:IPARAM(5)) = V(:,1:IPARAM(5)) * T, and c trans(V(:,1:IPARAM(5))) * V(:,1:IPARAM(5)) = I are approximately c satisfied. Here T is the leading submatrix of order IPARAM(5) of the c real upper quasi-triangular matrix stored workl(ipntr(12)). That is, c T is block upper triangular with 1-by-1 and 2-by-2 diagonal blocks; c each 2-by-2 diagonal block has its diagonal elements equal and its c off-diagonal elements of opposite sign. Corresponding to each 2-by-2 c diagonal block is a complex conjugate pair of Ritz values. The real c Ritz values are stored on the diagonal of T. c c 3. If IPARAM(7) = 3 or 4 and SIGMAI is not equal zero, then the user must c form the IPARAM(5) Rayleigh quotients in order to transform the Ritz c values computed by SNAUPD for OP to those of A*z = lambda*B*z. c Set RVEC = .true. and HOWMNY = 'A', and c compute c trans(Z(:,I)) * A * Z(:,I) if DI(I) = 0. c If DI(I) is not equal to zero and DI(I+1) = - D(I), c then the desired real and imaginary parts of the Ritz value are c trans(Z(:,I)) * A * Z(:,I) + trans(Z(:,I+1)) * A * Z(:,I+1), c trans(Z(:,I)) * A * Z(:,I+1) - trans(Z(:,I+1)) * A * Z(:,I), c respectively. c Another possibility is to set RVEC = .true. and HOWMNY = 'P' and c compute trans(V(:,1:IPARAM(5))) * A * V(:,1:IPARAM(5)) and then an upper c quasi-triangular matrix of order IPARAM(5) is computed.

An orthonormal c (Lanczos) basis is always computed. There is an additional storage cost c of n*nev if both are requested (in this case a separate array Z must be c supplied). c c These quantities are obtained from the Lanczos factorization computed c by SSAUPD for the linear operator OP prescribed by the MODE selection c (see IPARAM(7) in SSAUPD documentation.) SSAUPD must be called before c this routine is called. These approximate eigenvalues and vectors are c commonly called Ritz values and Ritz vectors respectively. They are c referred to as such in the comments that follow. The computed orthonormal c basis for the invariant subspace corresponding to these Ritz values is c referred to as a Lanczos basis. c c See documentation in the header of the subroutine SSAUPD for a definition c of OP as well as other terms and the relation of computed Ritz values c and vectors of OP with respect to the given problem A*z = lambda*B*z. c c The approximate eigenvalues of the original problem are returned in c ascending algebraic order. The user may elect to call this routine c once for each desired Ritz vector and store it peripherally if desired. c There is also the option of computing a selected set of these vectors c with a single call. c c\Usage: c call sseupd c ( RVEC, HOWMNY, SELECT, D, Z, LDZ, SIGMA, BMAT, N, WHICH, NEV, TOL, c RESID, NCV, V, LDV, IPARAM, IPNTR, WORKD, WORKL, LWORKL, INFO ) c c RVEC LOGICAL (INPUT) c Specifies whether Ritz vectors corresponding to the Ritz value c approximations to the eigenproblem A*z = lambda*B*z are computed. c c RVEC = .FALSE. Compute Ritz values only. c c RVEC = .TRUE. Compute Ritz vectors. c c HOWMNY Character*1 (INPUT) c Specifies how many Ritz vectors are wanted and the form of Z c the matrix of Ritz vectors. See remark 1 below. c = 'A': compute NEV Ritz vectors; c = 'S': compute some of the Ritz vectors, specified c by the logical array SELECT. c c SELECT Logical array of dimension NCV. (INPUT/WORKSPACE) c If HOWMNY = 'S', SELECT specifies the Ritz vectors to be c computed. To select the Ritz vector corresponding to a c Ritz value D(j), SELECT(j) must be set to .TRUE.. c If HOWMNY = 'A' , SELECT is used as a workspace for c reordering the Ritz values. c c D Real array of dimension NEV. (OUTPUT) c On exit, D contains the Ritz value approximations to the c eigenvalues of A*z = lambda*B*z. The values are returned c in ascending order. If IPARAM(7) = 3,4,5 then D represents c the Ritz values of OP computed by ssaupd transformed to c those of the original eigensystem A*z = lambda*B*z. If c IPARAM(7) = 1,2 then the Ritz values of OP are the same c as the those of A*z = lambda*B*z. c c Z Real N by NEV array if HOWMNY = 'A'. (OUTPUT) c On exit, Z contains the B-orthonormal Ritz vectors of the c eigensystem A*z = lambda*B*z corresponding to the Ritz c value approximations. c If RVEC = .FALSE. then Z is not referenced. c NOTE: The array Z may be set equal to first NEV columns of the c Arnoldi/Lanczos basis array V computed by SSAUPD. c c LDZ Integer.

(INPUT) c It is assumed that H is already upper quasi-triangular in c rows and columns IHI+1:N, and that H(ILO,ILO-1) = 0 (unless c ILO = 1).

If two eigenvalues are computed as a c complex conjugate pair, they are stored in consecutive c elements of WR and WI, say the i-th and (i+1)th, with c WI(i) > 0 and WI(i+1) < 0. If WANTT is .TRUE., the c eigenvalues are stored in the same order as on the diagonal c of the Schur form returned in H, with WR(i) = H(i,i), and, if c H(i:i+1,i:i+1) is a 2-by-2 diagonal block, c WI(i) = sqrt(H(i+1,i)*H(i,i+1)) and WI(i+1) = -WI(i). c c Z Double precision array, dimension (N).

(INPUT/OUTPUT) c Contains the number of implicit shifts to apply during c each Arnoldi iteration. c If ISHIFT=1, NP is adjusted dynamically at each iteration c to accelerate convergence and prevent stagnation. c This is also roughly equal to the number of matrix-vector c products (involving the operator OP) per Arnoldi iteration. c The logic for adjusting is contained within the current c subroutine. c If ISHIFT=0, NP is the number of shifts the user needs c to provide via reverse comunication. 0 < NP < NCV-NEV. c NP may be less than NCV-NEV for two reasons. The first, is c to keep complex conjugate pairs of "wanted" Ritz values c together. The second, is that a leading block of the current c upper Hessenberg matrix has split off and contains "unwanted" c Ritz values. c Upon termination of the IRA iteration, NP contains the number c of "converged" wanted Ritz values. c c IUPD Integer. (INPUT) c IUPD .EQ. 0: use explicit restart instead implicit update. c IUPD .NE. 0: use implicit update. c c V Double precision N by (NEV+NP) array. (INPUT/OUTPUT) c The Arnoldi basis vectors are returned in the first NEV c columns of V. c c LDV Integer.

(OUTPUT) c H is used to store the generated upper Hessenberg matrix c c LDH Integer. (INPUT) c Leading dimension of H exactly as declared in the calling c program. c c RITZR, Double precision arrays of length NEV+NP. (OUTPUT) c RITZI RITZR(1:NEV) (resp.

(OUTPUT) c BOUNDS(1:NEV) contain the error bounds corresponding to c the computed Ritz values. c c Q Double precision (NEV+NP) by (NEV+NP) array. (WORKSPACE) c Private (replicated) work array used to accumulate the c rotation in the shift application step. c c LDQ Integer. (INPUT) c Leading dimension of Q exactly as declared in the calling c program. c c WORKL Double precision work array of length at least c (NEV+NP)**2 + 3*(NEV+NP). (INPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. It is used in shifts calculation, shifts c application and convergence checking. c c On exit, the last 3*(NEV+NP) locations of WORKL contain c the Ritz values (real,imaginary) and associated Ritz c estimates of the current Hessenberg matrix. They are c listed in the same order as returned from dneigh. c c If ISHIFT .EQ. O and IDO .EQ. 3, the first 2*NP locations c of WORKL are used in reverse communication to hold the user c supplied shifts. c c IPNTR Integer array of length 3.

(WORKSPACE) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration !!!!!!!!!! c See Data Distribution Note in DNAUPD. c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal return. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. c NP returns the number of converged Ritz values. c = 2: No shifts could be applied. c = -8: Error return from LAPACK eigenvalue calculation; c This should never happen. c = -9: Starting vector is zero. c = -9999: Could not build an Arnoldi factorization. c Size that was built in returned in NP. c c\EndDoc c c----------------------------------------------------------------------- c c\BeginLib c c\Local variables: c xxxxxx real c c\References: c 1.

This subroutine computes approximations to a few eigenpairs c of a linear operator "OP" with respect to a semi-inner product defined by c a symmetric positive semi-definite real matrix B. B may be the identity c matrix. NOTE: If the linear operator "OP" is real and symmetric c with respect to the real positive semi-definite symmetric matrix B, c i.e. B*OP = (OP`)*B, then subroutine dsaupd should be used instead. c c The computed approximate eigenvalues are called Ritz values and c the corresponding approximate eigenvectors are called Ritz vectors. c c dnaupd is usually called iteratively to solve one of the c following problems: c c Mode 1: A*x = lambda*x. c ===> OP = A and B = I. c c Mode 2: A*x = lambda*M*x, M symmetric positive definite c ===> OP = inv[M]*A and B = M. c ===> (If M can be factored see remark 3 below) c c Mode 3: A*x = lambda*M*x, M symmetric semi-definite c ===> OP = Real_Part{ inv[A - sigma*M]*M } and B = M. c ===> shift-and-invert mode (in real arithmetic) c If OP*x = amu*x, then c amu = 1/2 * [ 1/(lambda-sigma) + 1/(lambda-conjg(sigma)) ]. c Note: If sigma is real, i.e. imaginary part of sigma is zero; c Real_Part{ inv[A - sigma*M]*M } == inv[A - sigma*M]*M c amu == 1/(lambda-sigma). c c Mode 4: A*x = lambda*M*x, M symmetric semi-definite c ===> OP = Imaginary_Part{ inv[A - sigma*M]*M } and B = M. c ===> shift-and-invert mode (in real arithmetic) c If OP*x = amu*x, then c amu = 1/2i * [ 1/(lambda-sigma) - 1/(lambda-conjg(sigma)) ]. c c Both mode 3 and 4 give the same enhancement to eigenvalues close to c the (complex) shift sigma. However, as lambda goes to infinity, c the operator OP in mode 4 dampens the eigenvalues more strongly than c does OP defined in mode 3. c c NOTE: The action of w <- inv[A - sigma*M]*v or w <- inv[M]*v c should be accomplished either by a direct method c using a sparse matrix factorization and solving c c [A - sigma*M]*w = v or M*w = v, c c or through an iterative method for solving these c systems. If an iterative method is used, the c convergence test must be more stringent than c the accuracy requirements for the eigenvalue c approximations. c c\Usage: c call dnaupd c ( IDO, BMAT, N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, c IPNTR, WORKD, WORKL, LWORKL, INFO ) c c\Arguments c IDO Integer. (INPUT/OUTPUT) c Reverse communication flag. IDO must be zero on the first c call to dnaupd. IDO will be set internally to c indicate the type of operation to be performed. Control is c then given back to the calling routine which has the c responsibility to carry out the requested operation and call c dnaupd with the result. The operand is given in c WORKD(IPNTR(1)), the result must be put in WORKD(IPNTR(2)). c ------------------------------------------------------------- c IDO = 0: first call to the reverse communication interface c IDO = -1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c This is for the initialization phase to force the c starting vector into the range of OP. c IDO = 1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c In mode 3 and 4, the vector B * X is already c available in WORKD(ipntr(3)). It does not c need to be recomputed in forming OP * X. c IDO = 2: compute Y = B * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c IDO = 3: compute the IPARAM(8) real and imaginary parts c of the shifts where INPTR(14) is the pointer c into WORKL for placing the shifts. See Remark c 5 below. c IDO = 99: done c ------------------------------------------------------------- c c BMAT Character*1. (INPUT) c BMAT specifies the type of the matrix B that defines the c semi-inner product for the operator OP. c BMAT = 'I' -> standard eigenvalue problem A*x = lambda*x c BMAT = 'G' -> generalized eigenvalue problem A*x = lambda*B*x c c N Integer. (INPUT) c Dimension of the eigenproblem. c c WHICH Character*2. (INPUT) c 'LM' -> want the NEV eigenvalues of largest magnitude. c 'SM' -> want the NEV eigenvalues of smallest magnitude. c 'LR' -> want the NEV eigenvalues of largest real part. c 'SR' -> want the NEV eigenvalues of smallest real part. c 'LI' -> want the NEV eigenvalues of largest imaginary part. c 'SI' -> want the NEV eigenvalues of smallest imaginary part. c c NEV Integer. (INPUT/OUTPUT) c Number of eigenvalues of OP to be computed. 0 < NEV < N-1. c c TOL Double precision scalar. (INPUT) c Stopping criterion: the relative accuracy of the Ritz value c is considered acceptable if BOUNDS(I) .LE. TOL*ABS(RITZ(I)) c where ABS(RITZ(I)) is the magnitude when RITZ(I) is complex. c DEFAULT = DLAMCH('EPS') (machine precision as computed c by the LAPACK auxiliary subroutine DLAMCH). c c RESID Double precision array of length N. (INPUT/OUTPUT) c On INPUT: c If INFO .EQ. 0, a random initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c On OUTPUT: c RESID contains the final residual vector. c c NCV Integer. (INPUT) c Number of columns of the matrix V. NCV must satisfy the two c inequalities 2 <= NCV-NEV and NCV <= N. c This will indicate how many Arnoldi vectors are generated c at each iteration. After the startup phase in which NEV c Arnoldi vectors are generated, the algorithm generates c approximately NCV-NEV Arnoldi vectors at each subsequent update c iteration. Most of the cost in generating each Arnoldi vector is c in the matrix-vector operation OP*x. c NOTE: 2 <= NCV-NEV in order that complex conjugate pairs of Ritz c values are kept together. (See remark 4 below) c c V Double precision array N by NCV. (OUTPUT) c Contains the final set of Arnoldi basis vectors. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling program. c c IPARAM Integer array of length 11. (INPUT/OUTPUT) c IPARAM(1) = ISHIFT: method for selecting the implicit shifts. c The shifts selected at each iteration are used to restart c the Arnoldi iteration in an implicit fashion. c ------------------------------------------------------------- c ISHIFT = 0: the shifts are provided by the user via c reverse communication. The real and imaginary c parts of the NCV eigenvalues of the Hessenberg c matrix H are returned in the part of the WORKL c array corresponding to RITZR and RITZI. See remark c 5 below. c ISHIFT = 1: exact shifts with respect to the current c Hessenberg matrix H. This is equivalent to c restarting the iteration with a starting vector c that is a linear combination of approximate Schur c vectors associated with the "wanted" Ritz values. c ------------------------------------------------------------- c c IPARAM(2) = No longer referenced. c c IPARAM(3) = MXITER c On INPUT: maximum number of Arnoldi update iterations allowed. c On OUTPUT: actual number of Arnoldi update iterations taken. c c IPARAM(4) = NB: blocksize to be used in the recurrence. c The code currently works only for NB = 1. c c IPARAM(5) = NCONV: number of "converged" Ritz values. c This represents the number of Ritz values that satisfy c the convergence criterion. c c IPARAM(6) = IUPD c No longer referenced. Implicit restarting is ALWAYS used. c c IPARAM(7) = MODE c On INPUT determines what type of eigenproblem is being solved. c Must be 1,2,3,4; See under \Description of dnaupd for the c four modes available. c c IPARAM(8) = NP c When ido = 3 and the user provides shifts through reverse c communication (IPARAM(1)=0), dnaupd returns NP, the number c of shifts the user is to provide. 0 < NP <=NCV-NEV. See Remark c 5 below. c c IPARAM(9) = NUMOP, IPARAM(10) = NUMOPB, IPARAM(11) = NUMREO, c OUTPUT: NUMOP = total number of OP*x operations, c NUMOPB = total number of B*x operations if BMAT='G', c NUMREO = total number of steps of re-orthogonalization. c c IPNTR Integer array of length 14. (OUTPUT) c Pointer to mark the starting locations in the WORKD and WORKL c arrays for matrices/vectors used by the Arnoldi iteration. c ------------------------------------------------------------- c IPNTR(1): pointer to the current operand vector X in WORKD. c IPNTR(2): pointer to the current result vector Y in WORKD. c IPNTR(3): pointer to the vector B * X in WORKD when used in c the shift-and-invert mode. c IPNTR(4): pointer to the next available location in WORKL c that is untouched by the program. c IPNTR(5): pointer to the NCV by NCV upper Hessenberg matrix c H in WORKL. c IPNTR(6): pointer to the real part of the ritz value array c RITZR in WORKL. c IPNTR(7): pointer to the imaginary part of the ritz value array c RITZI in WORKL. c IPNTR(8): pointer to the Ritz estimates in array WORKL associated c with the Ritz values located in RITZR and RITZI in WORKL. c c IPNTR(14): pointer to the NP shifts in WORKL. See Remark 5 below. c c Note: IPNTR(9:13) is only referenced by dneupd. See Remark 2 below. c c IPNTR(9): pointer to the real part of the NCV RITZ values of the c original system. c IPNTR(10): pointer to the imaginary part of the NCV RITZ values of c the original system. c IPNTR(11): pointer to the NCV corresponding error bounds. c IPNTR(12): pointer to the NCV by NCV upper quasi-triangular c Schur matrix for H. c IPNTR(13): pointer to the NCV by NCV matrix of eigenvectors c of the upper Hessenberg matrix H. Only referenced by c dneupd if RVEC = .TRUE. See Remark 2 below. c ------------------------------------------------------------- c c WORKD Double precision work array of length 3*N. (REVERSE COMMUNICATION) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration. Upon termination c WORKD(1:N) contains B*RESID(1:N). If an invariant subspace c associated with the converged Ritz values is desired, see remark c 2 below, subroutine dneupd uses this output. c See Data Distribution Note below. c c WORKL Double precision work array of length LWORKL. (OUTPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. See Data Distribution Note below. c c LWORKL Integer. (INPUT) c LWORKL must be at least 3*NCV**2 + 6*NCV. c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal exit. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. IPARAM(5) c returns the number of wanted converged Ritz values. c = 2: No longer an informational error. Deprecated starting c with release 2 of ARPACK. c = 3: No shifts could be applied during a cycle of the c Implicitly restarted Arnoldi iteration. One possibility c is to increase the size of NCV relative to NEV. c See remark 4 below. c = -1: N must be positive. c = -2: NEV must be positive. c = -3: NCV-NEV >= 2 and less than or equal to N. c = -4: The maximum number of Arnoldi update iteration c must be greater than zero. c = -5: WHICH must be one of 'LM', 'SM', 'LR', 'SR', 'LI', 'SI' c = -6: BMAT must be one of 'I' or 'G'. c = -7: Length of private work array is not sufficient. c = -8: Error return from LAPACK eigenvalue calculation; c = -9: Starting vector is zero. c = -10: IPARAM(7) must be 1,2,3,4. c = -11: IPARAM(7) = 1 and BMAT = 'G' are incompatable. c = -12: IPARAM(1) must be equal to 0 or 1. c = -9999: Could not build an Arnoldi factorization. c IPARAM(5) returns the size of the current Arnoldi c factorization. c c\Remarks c 1. The computed Ritz values are approximate eigenvalues of OP. The c selection of WHICH should be made with this in mind when c Mode = 3 and 4. After convergence, approximate eigenvalues of the c original problem may be obtained with the ARPACK subroutine dneupd. c c 2. If a basis for the invariant subspace corresponding to the converged Ritz c values is needed, the user must call dneupd immediately following c completion of dnaupd. This is new starting with release 2 of ARPACK. c c 3. If M can be factored into a Cholesky factorization M = LL` c then Mode = 2 should not be selected. Instead one should use c Mode = 1 with OP = inv(L)*A*inv(L`). Appropriate triangular c linear systems should be solved with L and L` rather c than computing inverses. After convergence, an approximate c eigenvector z of the original problem is recovered by solving c L`z = x where x is a Ritz vector of OP. c c 4. At present there is no a-priori analysis to guide the selection c of NCV relative to NEV. The only formal requrement is that NCV > NEV + 2. c However, it is recommended that NCV .ge. 2*NEV+1. If many problems of c the same type are to be solved, one should experiment with increasing c NCV while keeping NEV fixed for a given test problem. This will c usually decrease the required number of OP*x operations but it c also increases the work and storage required to maintain the orthogonal c basis vectors. The optimal "cross-over" with respect to CPU time c is problem dependent and must be determined empirically. c See Chapter 8 of Reference 2 for further information. c c 5. When IPARAM(1) = 0, and IDO = 3, the user needs to provide the c NP = IPARAM(8) real and imaginary parts of the shifts in locations c real part imaginary part c ----------------------- -------------- c 1 WORKL(IPNTR(14)) WORKL(IPNTR(14)+NP) c 2 WORKL(IPNTR(14)+1) WORKL(IPNTR(14)+NP+1) c . . c . . c . . c NP WORKL(IPNTR(14)+NP-1) WORKL(IPNTR(14)+2*NP-1). c c Only complex conjugate pairs of shifts may be applied and the pairs c must be placed in consecutive locations.

(INPUT/OUTPUT) c Reverse communication flag. c ------------------------------------------------------------- c IDO = 0: first call to the reverse communication interface c IDO = -1: compute Y = OP * X where c IPNTR(1) is the pointer into WORK for X, c IPNTR(2) is the pointer into WORK for Y. c This is for the restart phase to force the new c starting vector into the range of OP. c IDO = 1: compute Y = OP * X where c IPNTR(1) is the pointer into WORK for X, c IPNTR(2) is the pointer into WORK for Y, c IPNTR(3) is the pointer into WORK for B * X. c IDO = 2: compute Y = B * X where c IPNTR(1) is the pointer into WORK for X, c IPNTR(2) is the pointer into WORK for Y. c IDO = 99: done c ------------------------------------------------------------- c When the routine is used in the "shift-and-invert" mode, the c vector B * Q is already available and does not need to be c recomputed in forming OP * Q. c c BMAT Character*1. (INPUT) c BMAT specifies the type of matrix B that defines the c semi-inner product for the operator OP. See dsaupd. c B = 'I' -> standard eigenvalue problem A*x = lambda*x c B = 'G' -> generalized eigenvalue problem A*x = lambda*M*x c c N Integer. (INPUT) c Dimension of the eigenproblem. c c K Integer. (INPUT) c Current order of H and the number of columns of V. c c NP Integer. (INPUT) c Number of additional Arnoldi steps to take. c c MODE Integer. (INPUT) c Signifies which form for "OP". If MODE=2 then c a reduction in the number of B matrix vector multiplies c is possible since the B-norm of OP*x is equivalent to c the inv(B)-norm of A*x. c c RESID Double precision array of length N. (INPUT/OUTPUT) c On INPUT: RESID contains the residual vector r_{k}. c On OUTPUT: RESID contains the residual vector r_{k+p}. c c RNORM Double precision scalar. (INPUT/OUTPUT) c On INPUT the B-norm of r_{k}. c On OUTPUT the B-norm of the updated residual r_{k+p}. c c V Double precision N by K+NP array. (INPUT/OUTPUT) c On INPUT: V contains the Arnoldi vectors in the first K c columns. c On OUTPUT: V contains the new NP Arnoldi vectors in the next c NP columns. The first K columns are unchanged. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling c program. c c H Double precision (K+NP) by 2 array. (INPUT/OUTPUT) c H is used to store the generated symmetric tridiagonal matrix c with the subdiagonal in the first column starting at H(2,1) c and the main diagonal in the second column. c c LDH Integer. (INPUT) c Leading dimension of H exactly as declared in the calling c program. c c IPNTR Integer array of length 3. (OUTPUT) c Pointer to mark the starting locations in the WORK for c vectors used by the Arnoldi iteration. c ------------------------------------------------------------- c IPNTR(1): pointer to the current operand vector X. c IPNTR(2): pointer to the current result vector Y. c IPNTR(3): pointer to the vector B * X when used in the c shift-and-invert mode. X is the current operand. c ------------------------------------------------------------- c c WORKD Double precision work array of length 3*N. (REVERSE COMMUNICATION) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The calling program should not c use WORKD as temporary workspace during the iteration !!!!!! c On INPUT, WORKD(1:N) = B*RESID where RESID is associated c with the K step Arnoldi factorization. Used to save some c computation at the first step. c On OUTPUT, WORKD(1:N) = B*RESID where RESID is associated c with the K+NP step Arnoldi factorization. c c INFO Integer. (OUTPUT) c = 0: Normal exit. c > 0: Size of an invariant subspace of OP is found that is c less than K + NP. c c\EndDoc c c----------------------------------------------------------------------- c c\BeginLib c c\Local variables: c xxxxxx real c c\Routines called: c dgetv0 ARPACK routine to generate the initial vector. c ivout ARPACK utility routine that prints integers. c dmout ARPACK utility routine that prints matrices. c dvout ARPACK utility routine that prints vectors. c dlamch LAPACK routine that determines machine constants. c dlascl LAPACK routine for careful scaling of a matrix. c dgemv Level 2 BLAS routine for matrix vector multiplication. c daxpy Level 1 BLAS that computes a vector triad. c dscal Level 1 BLAS that scales a vector. c dcopy Level 1 BLAS that copies one vector to another . c ddot Level 1 BLAS that computes the scalar product of two vectors. c dnrm2 Level 1 BLAS that computes the norm of a vector. c c\Author c Danny Sorensen Phuong Vu c Richard Lehoucq CRPC / Rice University c Dept. of Computational & Houston, Texas c Applied Mathematics c Rice University c Houston, Texas c c\Revision history: c xx/xx/93: Version ' 2.4' c c\SCCS Information: @(#) c FILE: saitr.F SID: 2.6 DATE OF SID: 8/28/96 RELEASE: 2 c c\Remarks c The algorithm implemented is: c c restart = .false. c Given V_{k} = [v_{1}, ..., v_{k}], r_{k};

For symmetric problems this reduces to a variant of the Lanczos c method. This method has been designed to compute approximations to a c few eigenpairs of a linear operator OP that is real and symmetric c with respect to a real positive semi-definite symmetric matrix B, c i.e. c c B*OP = (OP`)*B. c c Another way to express this condition is c c < x,OPy > = < OPx,y > where < z,w > = z`Bw . c c In the standard eigenproblem B is the identity matrix. c ( A` denotes transpose of A) c c The computed approximate eigenvalues are called Ritz values and c the corresponding approximate eigenvectors are called Ritz vectors. c c dsaupd is usually called iteratively to solve one of the c following problems: c c Mode 1: A*x = lambda*x, A symmetric c ===> OP = A and B = I. c c Mode 2: A*x = lambda*M*x, A symmetric, M symmetric positive definite c ===> OP = inv[M]*A and B = M. c ===> (If M can be factored see remark 3 below) c c Mode 3: K*x = lambda*M*x, K symmetric, M symmetric positive semi-definite c ===> OP = (inv[K - sigma*M])*M and B = M. c ===> Shift-and-Invert mode c c Mode 4: K*x = lambda*KG*x, K symmetric positive semi-definite, c KG symmetric indefinite c ===> OP = (inv[K - sigma*KG])*K and B = K. c ===> Buckling mode c c Mode 5: A*x = lambda*M*x, A symmetric, M symmetric positive semi-definite c ===> OP = inv[A - sigma*M]*[A + sigma*M] and B = M. c ===> Cayley transformed mode c c NOTE: The action of w <- inv[A - sigma*M]*v or w <- inv[M]*v c should be accomplished either by a direct method c using a sparse matrix factorization and solving c c [A - sigma*M]*w = v or M*w = v, c c or through an iterative method for solving these c systems. If an iterative method is used, the c convergence test must be more stringent than c the accuracy requirements for the eigenvalue c approximations. c c\Usage: c call dsaupd c ( IDO, BMAT, N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, c IPNTR, WORKD, WORKL, LWORKL, INFO ) c c\Arguments c IDO Integer. (INPUT/OUTPUT) c Reverse communication flag. IDO must be zero on the first c call to dsaupd . IDO will be set internally to c indicate the type of operation to be performed. Control is c then given back to the calling routine which has the c responsibility to carry out the requested operation and call c dsaupd with the result. The operand is given in c WORKD(IPNTR(1)), the result must be put in WORKD(IPNTR(2)). c (If Mode = 2 see remark 5 below) c ------------------------------------------------------------- c IDO = 0: first call to the reverse communication interface c IDO = -1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c This is for the initialization phase to force the c starting vector into the range of OP. c IDO = 1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c In mode 3,4 and 5, the vector B * X is already c available in WORKD(ipntr(3)). It does not c need to be recomputed in forming OP * X. c IDO = 2: compute Y = B * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c IDO = 3: compute the IPARAM(8) shifts where c IPNTR(11) is the pointer into WORKL for c placing the shifts. See remark 6 below. c IDO = 99: done c ------------------------------------------------------------- c c BMAT Character*1. (INPUT) c BMAT specifies the type of the matrix B that defines the c semi-inner product for the operator OP. c B = 'I' -> standard eigenvalue problem A*x = lambda*x c B = 'G' -> generalized eigenvalue problem A*x = lambda*B*x c c N Integer. (INPUT) c Dimension of the eigenproblem. c c WHICH Character*2. (INPUT) c Specify which of the Ritz values of OP to compute. c c 'LA' - compute the NEV largest (algebraic) eigenvalues. c 'SA' - compute the NEV smallest (algebraic) eigenvalues. c 'LM' - compute the NEV largest (in magnitude) eigenvalues. c 'SM' - compute the NEV smallest (in magnitude) eigenvalues. c 'BE' - compute NEV eigenvalues, half from each end of the c spectrum. When NEV is odd, compute one more from the c high end than from the low end. c (see remark 1 below) c c NEV Integer. (INPUT) c Number of eigenvalues of OP to be computed. 0 < NEV < N. c c TOL Double precision scalar. (INPUT) c Stopping criterion: the relative accuracy of the Ritz value c is considered acceptable if BOUNDS(I) .LE. TOL*ABS(RITZ(I)). c If TOL .LE. 0. is passed a default is set: c DEFAULT = DLAMCH ('EPS') (machine precision as computed c by the LAPACK auxiliary subroutine DLAMCH ). c c RESID Double precision array of length N. (INPUT/OUTPUT) c On INPUT: c If INFO .EQ. 0, a random initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c On OUTPUT: c RESID contains the final residual vector. c c NCV Integer. (INPUT) c Number of columns of the matrix V (less than or equal to N). c This will indicate how many Lanczos vectors are generated c at each iteration. After the startup phase in which NEV c Lanczos vectors are generated, the algorithm generates c NCV-NEV Lanczos vectors at each subsequent update iteration. c Most of the cost in generating each Lanczos vector is in the c matrix-vector product OP*x. (See remark 4 below). c c V Double precision N by NCV array. (OUTPUT) c The NCV columns of V contain the Lanczos basis vectors. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling c program. c c IPARAM Integer array of length 11. (INPUT/OUTPUT) c IPARAM(1) = ISHIFT: method for selecting the implicit shifts. c The shifts selected at each iteration are used to restart c the Arnoldi iteration in an implicit fashion. c ------------------------------------------------------------- c ISHIFT = 0: the shifts are provided by the user via c reverse communication. The NCV eigenvalues of c the current tridiagonal matrix T are returned in c the part of WORKL array corresponding to RITZ. c See remark 6 below. c ISHIFT = 1: exact shifts with respect to the reduced c tridiagonal matrix T. This is equivalent to c restarting the iteration with a starting vector c that is a linear combination of Ritz vectors c associated with the "wanted" Ritz values. c ------------------------------------------------------------- c c IPARAM(2) = LEVEC c No longer referenced. See remark 2 below. c c IPARAM(3) = MXITER c On INPUT: maximum number of Arnoldi update iterations allowed. c On OUTPUT: actual number of Arnoldi update iterations taken. c c IPARAM(4) = NB: blocksize to be used in the recurrence. c The code currently works only for NB = 1. c c IPARAM(5) = NCONV: number of "converged" Ritz values. c This represents the number of Ritz values that satisfy c the convergence criterion. c c IPARAM(6) = IUPD c No longer referenced. Implicit restarting is ALWAYS used. c c IPARAM(7) = MODE c On INPUT determines what type of eigenproblem is being solved. c Must be 1,2,3,4,5; See under \Description of dsaupd for the c five modes available. c c IPARAM(8) = NP c When ido = 3 and the user provides shifts through reverse c communication (IPARAM(1)=0), dsaupd returns NP, the number c of shifts the user is to provide. 0 < NP <=NCV-NEV. See Remark c 6 below. c c IPARAM(9) = NUMOP, IPARAM(10) = NUMOPB, IPARAM(11) = NUMREO, c OUTPUT: NUMOP = total number of OP*x operations, c NUMOPB = total number of B*x operations if BMAT='G', c NUMREO = total number of steps of re-orthogonalization. c c IPNTR Integer array of length 11. (OUTPUT) c Pointer to mark the starting locations in the WORKD and WORKL c arrays for matrices/vectors used by the Lanczos iteration. c ------------------------------------------------------------- c IPNTR(1): pointer to the current operand vector X in WORKD. c IPNTR(2): pointer to the current result vector Y in WORKD. c IPNTR(3): pointer to the vector B * X in WORKD when used in c the shift-and-invert mode. c IPNTR(4): pointer to the next available location in WORKL c that is untouched by the program. c IPNTR(5): pointer to the NCV by 2 tridiagonal matrix T in WORKL. c IPNTR(6): pointer to the NCV RITZ values array in WORKL. c IPNTR(7): pointer to the Ritz estimates in array WORKL associated c with the Ritz values located in RITZ in WORKL. c IPNTR(11): pointer to the NP shifts in WORKL.

Only referenced by c dseupd if RVEC = .TRUE. See Remarks. c ------------------------------------------------------------- c c WORKD Double precision work array of length 3*N. (REVERSE COMMUNICATION) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration. Upon termination c WORKD(1:N) contains B*RESID(1:N). If the Ritz vectors are desired c subroutine dseupd uses this output. c See Data Distribution Note below. c c WORKL Double precision work array of length LWORKL. (OUTPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. See Data Distribution Note below. c c LWORKL Integer. (INPUT) c LWORKL must be at least NCV**2 + 8*NCV . c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal exit. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. IPARAM(5) c returns the number of wanted converged Ritz values. c = 2: No longer an informational error. Deprecated starting c with release 2 of ARPACK. c = 3: No shifts could be applied during a cycle of the c Implicitly restarted Arnoldi iteration. One possibility c is to increase the size of NCV relative to NEV. c See remark 4 below. c = -1: N must be positive. c = -2: NEV must be positive. c = -3: NCV must be greater than NEV and less than or equal to N. c = -4: The maximum number of Arnoldi update iterations allowed c must be greater than zero. c = -5: WHICH must be one of 'LM', 'SM', 'LA', 'SA' or 'BE'. c = -6: BMAT must be one of 'I' or 'G'. c = -7: Length of private work array WORKL is not sufficient. c = -8: Error return from trid. eigenvalue calculation; c Informatinal error from LAPACK routine dsteqr . c = -9: Starting vector is zero. c = -10: IPARAM(7) must be 1,2,3,4,5. c = -11: IPARAM(7) = 1 and BMAT = 'G' are incompatable. c = -12: IPARAM(1) must be equal to 0 or 1. c = -13: NEV and WHICH = 'BE' are incompatable. c = -9999: Could not build an Arnoldi factorization. c IPARAM(5) returns the size of the current Arnoldi c factorization. The user is advised to check that c enough workspace and array storage has been allocated. c c c\Remarks c 1. The converged Ritz values are always returned in ascending c algebraic order. The computed Ritz values are approximate c eigenvalues of OP. The selection of WHICH should be made c with this in mind when Mode = 3,4,5. After convergence, c approximate eigenvalues of the original problem may be obtained c with the ARPACK subroutine dseupd . c c 2. If the Ritz vectors corresponding to the converged Ritz values c are needed, the user must call dseupd immediately following completion c of dsaupd . This is new starting with version 2.1 of ARPACK. c c 3. If M can be factored into a Cholesky factorization M = LL` c then Mode = 2 should not be selected. Instead one should use c Mode = 1 with OP = inv(L)*A*inv(L`). Appropriate triangular c linear systems should be solved with L and L` rather c than computing inverses. After convergence, an approximate c eigenvector z of the original problem is recovered by solving c L`z = x where x is a Ritz vector of OP. c c 4. At present there is no a-priori analysis to guide the selection c of NCV relative to NEV. The only formal requrement is that NCV > NEV. c However, it is recommended that NCV .ge. 2*NEV. If many problems of c the same type are to be solved, one should experiment with increasing c NCV while keeping NEV fixed for a given test problem. This will c usually decrease the required number of OP*x operations but it c also increases the work and storage required to maintain the orthogonal c basis vectors. The optimal "cross-over" with respect to CPU time c is problem dependent and must be determined empirically. c c 5. If IPARAM(7) = 2 then in the Reverse commuication interface the user c must do the following. When IDO = 1, Y = OP * X is to be computed. c When IPARAM(7) = 2 OP = inv(B)*A. After computing A*X the user c must overwrite X with A*X. Y is then the solution to the linear set c of equations B*Y = A*X. c c 6. When IPARAM(1) = 0, and IDO = 3, the user needs to provide the c NP = IPARAM(8) shifts in locations: c 1 WORKL(IPNTR(11)) c 2 WORKL(IPNTR(11)+1) c . c . c . c NP WORKL(IPNTR(11)+NP-1). c c The eigenvalues of the current tridiagonal matrix are located in c WORKL(IPNTR(6)) through WORKL(IPNTR(6)+NCV-1). They are in the c order defined by WHICH. The associated Ritz estimates are located in c WORKL(IPNTR(8)), WORKL(IPNTR(8)+1), ... , WORKL(IPNTR(8)+NCV-1). c c----------------------------------------------------------------------- c c\Data Distribution Note: c c Fortran-D syntax: c ================ c REAL RESID(N), V(LDV,NCV), WORKD(3*N), WORKL(LWORKL) c DECOMPOSE D1(N), D2(N,NCV) c ALIGN RESID(I) with D1(I) c ALIGN V(I,J) with D2(I,J) c ALIGN WORKD(I) with D1(I) range (1:N) c ALIGN WORKD(I) with D1(I-N) range (N+1:2*N) c ALIGN WORKD(I) with D1(I-2*N) range (2*N+1:3*N) c DISTRIBUTE D1(BLOCK), D2(BLOCK,:) c REPLICATED WORKL(LWORKL) c c Cray MPP syntax: c =============== c REAL RESID(N), V(LDV,NCV), WORKD(N,3), WORKL(LWORKL) c SHARED RESID(BLOCK), V(BLOCK,:), WORKD(BLOCK,:) c REPLICATED WORKL(LWORKL) c c c\BeginLib c c\References: c 1.

An orthonormal c basis is always computed. There is an additional storage cost of n*nev c if both are requested (in this case a separate array Z must be supplied). c c The approximate eigenvalues and eigenvectors of A*z = lambda*B*z c are derived from approximate eigenvalues and eigenvectors of c of the linear operator OP prescribed by the MODE selection in the c call to DNAUPD . DNAUPD must be called before this routine is called. c These approximate eigenvalues and vectors are commonly called Ritz c values and Ritz vectors respectively. They are referred to as such c in the comments that follow. The computed orthonormal basis for the c invariant subspace corresponding to these Ritz values is referred to as a c Schur basis. c c See documentation in the header of the subroutine DNAUPD for c definition of OP as well as other terms and the relation of computed c Ritz values and Ritz vectors of OP with respect to the given problem c A*z = lambda*B*z. For a brief description, see definitions of c IPARAM(7), MODE and WHICH in the documentation of DNAUPD . c c\Usage: c call dneupd c ( RVEC, HOWMNY, SELECT, DR, DI, Z, LDZ, SIGMAR, SIGMAI, WORKEV, BMAT, c N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, IPNTR, WORKD, WORKL, c LWORKL, INFO ) c c\Arguments: c RVEC LOGICAL (INPUT) c Specifies whether a basis for the invariant subspace corresponding c to the converged Ritz value approximations for the eigenproblem c A*z = lambda*B*z is computed. c c RVEC = .FALSE. Compute Ritz values only. c c RVEC = .TRUE. Compute the Ritz vectors or Schur vectors. c See Remarks below. c c HOWMNY Character*1 (INPUT) c Specifies the form of the basis for the invariant subspace c corresponding to the converged Ritz values that is to be computed. c c = 'A': Compute NEV Ritz vectors; c = 'P': Compute NEV Schur vectors; c = 'S': compute some of the Ritz vectors, specified c by the logical array SELECT. c c SELECT Logical array of dimension NCV. (INPUT) c If HOWMNY = 'S', SELECT specifies the Ritz vectors to be c computed. To select the Ritz vector corresponding to a c Ritz value (DR(j), DI(j)), SELECT(j) must be set to .TRUE.. c If HOWMNY = 'A' or 'P', SELECT is used as internal workspace. c c DR Double precision array of dimension NEV+1. (OUTPUT) c If IPARAM(7) = 1,2 or 3 and SIGMAI=0.0 then on exit: DR contains c the real part of the Ritz approximations to the eigenvalues of c A*z = lambda*B*z. c If IPARAM(7) = 3, 4 and SIGMAI is not equal to zero, then on exit: c DR contains the real part of the Ritz values of OP computed by c DNAUPD . A further computation must be performed by the user c to transform the Ritz values computed for OP by DNAUPD to those c of the original system A*z = lambda*B*z. See remark 3 below. c c DI Double precision array of dimension NEV+1. (OUTPUT) c On exit, DI contains the imaginary part of the Ritz value c approximations to the eigenvalues of A*z = lambda*B*z associated c with DR. c c NOTE: When Ritz values are complex, they will come in complex c conjugate pairs. If eigenvectors are requested, the c corresponding Ritz vectors will also come in conjugate c pairs and the real and imaginary parts of these are c represented in two consecutive columns of the array Z c (see below). c c Z Double precision N by NEV+1 array if RVEC = .TRUE. and HOWMNY = 'A'. (OUTPUT) c On exit, if RVEC = .TRUE. and HOWMNY = 'A', then the columns of c Z represent approximate eigenvectors (Ritz vectors) corresponding c to the NCONV=IPARAM(5) Ritz values for eigensystem c A*z = lambda*B*z. c c The complex Ritz vector associated with the Ritz value c with positive imaginary part is stored in two consecutive c columns. The first column holds the real part of the Ritz c vector and the second column holds the imaginary part. The c Ritz vector associated with the Ritz value with negative c imaginary part is simply the complex conjugate of the Ritz vector c associated with the positive imaginary part. c c If RVEC = .FALSE. or HOWMNY = 'P', then Z is not referenced. c c NOTE: If if RVEC = .TRUE. and a Schur basis is not required, c the array Z may be set equal to first NEV+1 columns of the Arnoldi c basis array V computed by DNAUPD . In this case the Arnoldi basis c will be destroyed and overwritten with the eigenvector basis. c c LDZ Integer. (INPUT) c The leading dimension of the array Z. If Ritz vectors are c desired, then LDZ >= max( 1, N ). In any case, LDZ >= 1. c c SIGMAR Double precision (INPUT) c If IPARAM(7) = 3 or 4, represents the real part of the shift. c Not referenced if IPARAM(7) = 1 or 2. c c SIGMAI Double precision (INPUT) c If IPARAM(7) = 3 or 4, represents the imaginary part of the shift. c Not referenced if IPARAM(7) = 1 or 2. See remark 3 below. c c WORKEV Double precision work array of dimension 3*NCV. (WORKSPACE) c c **** The remaining arguments MUST be the same as for the **** c **** call to DNAUPD that was just completed. **** c c NOTE: The remaining arguments c c BMAT, N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, IPNTR, c WORKD, WORKL, LWORKL, INFO c c must be passed directly to DNEUPD following the last call c to DNAUPD . These arguments MUST NOT BE MODIFIED between c the the last call to DNAUPD and the call to DNEUPD . c c Three of these parameters (V, WORKL, INFO) are also output parameters: c c V Double precision N by NCV array. (INPUT/OUTPUT) c c Upon INPUT: the NCV columns of V contain the Arnoldi basis c vectors for OP as constructed by DNAUPD . c c Upon OUTPUT: If RVEC = .TRUE. the first NCONV=IPARAM(5) columns c contain approximate Schur vectors that span the c desired invariant subspace. See Remark 2 below. c c NOTE: If the array Z has been set equal to first NEV+1 columns c of the array V and RVEC=.TRUE. and HOWMNY= 'A', then the c Arnoldi basis held by V has been overwritten by the desired c Ritz vectors. If a separate array Z has been passed then c the first NCONV=IPARAM(5) columns of V will contain approximate c Schur vectors that span the desired invariant subspace. c c WORKL Double precision work array of length LWORKL. (OUTPUT/WORKSPACE) c WORKL(1:ncv*ncv+3*ncv) contains information obtained in c dnaupd . They are not changed by dneupd . c WORKL(ncv*ncv+3*ncv+1:3*ncv*ncv+6*ncv) holds the c real and imaginary part of the untransformed Ritz values, c the upper quasi-triangular matrix for H, and the c associated matrix representation of the invariant subspace for H. c c Note: IPNTR(9:13) contains the pointer into WORKL for addresses c of the above information computed by dneupd . c ------------------------------------------------------------- c IPNTR(9): pointer to the real part of the NCV RITZ values of the c original system. c IPNTR(10): pointer to the imaginary part of the NCV RITZ values of c the original system. c IPNTR(11): pointer to the NCV corresponding error bounds. c IPNTR(12): pointer to the NCV by NCV upper quasi-triangular c Schur matrix for H. c IPNTR(13): pointer to the NCV by NCV matrix of eigenvectors c of the upper Hessenberg matrix H. Only referenced by c dneupd if RVEC = .TRUE. See Remark 2 below. c ------------------------------------------------------------- c c INFO Integer. (OUTPUT) c Error flag on output. c c = 0: Normal exit. c c = 1: The Schur form computed by LAPACK routine dlahqr c could not be reordered by LAPACK routine dtrsen . c Re-enter subroutine dneupd with IPARAM(5)=NCV and c increase the size of the arrays DR and DI to have c dimension at least dimension NCV and allocate at least NCV c columns for Z.

Currently only HOWMNY = 'A' and 'P' are implemented. c c Let trans(X) denote the transpose of X. c c 2. Schur vectors are an orthogonal representation for the basis of c Ritz vectors. Thus, their numerical properties are often superior. c If RVEC = .TRUE. then the relationship c A * V(:,1:IPARAM(5)) = V(:,1:IPARAM(5)) * T, and c trans(V(:,1:IPARAM(5))) * V(:,1:IPARAM(5)) = I are approximately c satisfied. Here T is the leading submatrix of order IPARAM(5) of the c real upper quasi-triangular matrix stored workl(ipntr(12)). That is, c T is block upper triangular with 1-by-1 and 2-by-2 diagonal blocks; c each 2-by-2 diagonal block has its diagonal elements equal and its c off-diagonal elements of opposite sign. Corresponding to each 2-by-2 c diagonal block is a complex conjugate pair of Ritz values. The real c Ritz values are stored on the diagonal of T. c c 3. If IPARAM(7) = 3 or 4 and SIGMAI is not equal zero, then the user must c form the IPARAM(5) Rayleigh quotients in order to transform the Ritz c values computed by DNAUPD for OP to those of A*z = lambda*B*z. c Set RVEC = .true. and HOWMNY = 'A', and c compute c trans(Z(:,I)) * A * Z(:,I) if DI(I) = 0. c If DI(I) is not equal to zero and DI(I+1) = - D(I), c then the desired real and imaginary parts of the Ritz value are c trans(Z(:,I)) * A * Z(:,I) + trans(Z(:,I+1)) * A * Z(:,I+1), c trans(Z(:,I)) * A * Z(:,I+1) - trans(Z(:,I+1)) * A * Z(:,I), c respectively. c Another possibility is to set RVEC = .true. and HOWMNY = 'P' and c compute trans(V(:,1:IPARAM(5))) * A * V(:,1:IPARAM(5)) and then an upper c quasi-triangular matrix of order IPARAM(5) is computed.

An orthonormal c (Lanczos) basis is always computed. There is an additional storage cost c of n*nev if both are requested (in this case a separate array Z must be c supplied). c c These quantities are obtained from the Lanczos factorization computed c by DSAUPD for the linear operator OP prescribed by the MODE selection c (see IPARAM(7) in DSAUPD documentation.) DSAUPD must be called before c this routine is called. These approximate eigenvalues and vectors are c commonly called Ritz values and Ritz vectors respectively. They are c referred to as such in the comments that follow. The computed orthonormal c basis for the invariant subspace corresponding to these Ritz values is c referred to as a Lanczos basis. c c See documentation in the header of the subroutine DSAUPD for a definition c of OP as well as other terms and the relation of computed Ritz values c and vectors of OP with respect to the given problem A*z = lambda*B*z. c c The approximate eigenvalues of the original problem are returned in c ascending algebraic order.

This is intended to be used to find a few eigenpairs of a c complex linear operator OP with respect to a semi-inner product defined c by a hermitian positive semi-definite real matrix B. B may be the identity c matrix. NOTE: if both OP and B are real, then ssaupd or snaupd should c be used. c c c The computed approximate eigenvalues are called Ritz values and c the corresponding approximate eigenvectors are called Ritz vectors. c c cnaupd is usually called iteratively to solve one of the c following problems: c c Mode 1: A*x = lambda*x. c ===> OP = A and B = I. c c Mode 2: A*x = lambda*M*x, M hermitian positive definite c ===> OP = inv[M]*A and B = M. c ===> (If M can be factored see remark 3 below) c c Mode 3: A*x = lambda*M*x, M hermitian semi-definite c ===> OP = inv[A - sigma*M]*M and B = M. c ===> shift-and-invert mode c If OP*x = amu*x, then lambda = sigma + 1/amu. c c c NOTE: The action of w <- inv[A - sigma*M]*v or w <- inv[M]*v c should be accomplished either by a direct method c using a sparse matrix factorization and solving c c [A - sigma*M]*w = v or M*w = v, c c or through an iterative method for solving these c systems. If an iterative method is used, the c convergence test must be more stringent than c the accuracy requirements for the eigenvalue c approximations. c c\Usage: c call cnaupd c ( IDO, BMAT, N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, c IPNTR, WORKD, WORKL, LWORKL, RWORK, INFO ) c c\Arguments c IDO Integer. (INPUT/OUTPUT) c Reverse communication flag. IDO must be zero on the first c call to cnaupd. IDO will be set internally to c indicate the type of operation to be performed. Control is c then given back to the calling routine which has the c responsibility to carry out the requested operation and call c cnaupd with the result. The operand is given in c WORKD(IPNTR(1)), the result must be put in WORKD(IPNTR(2)). c ------------------------------------------------------------- c IDO = 0: first call to the reverse communication interface c IDO = -1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c This is for the initialization phase to force the c starting vector into the range of OP. c IDO = 1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c In mode 3, the vector B * X is already c available in WORKD(ipntr(3)). It does not c need to be recomputed in forming OP * X. c IDO = 2: compute Y = M * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c IDO = 3: compute and return the shifts in the first c NP locations of WORKL. c IDO = 99: done c ------------------------------------------------------------- c After the initialization phase, when the routine is used in c the "shift-and-invert" mode, the vector M * X is already c available and does not need to be recomputed in forming OP*X. c c BMAT Character*1. (INPUT) c BMAT specifies the type of the matrix B that defines the c semi-inner product for the operator OP. c BMAT = 'I' -> standard eigenvalue problem A*x = lambda*x c BMAT = 'G' -> generalized eigenvalue problem A*x = lambda*M*x c c N Integer. (INPUT) c Dimension of the eigenproblem. c c WHICH Character*2. (INPUT) c 'LM' -> want the NEV eigenvalues of largest magnitude. c 'SM' -> want the NEV eigenvalues of smallest magnitude. c 'LR' -> want the NEV eigenvalues of largest real part. c 'SR' -> want the NEV eigenvalues of smallest real part. c 'LI' -> want the NEV eigenvalues of largest imaginary part. c 'SI' -> want the NEV eigenvalues of smallest imaginary part. c c NEV Integer. (INPUT) c Number of eigenvalues of OP to be computed. 0 < NEV < N-1. c c TOL Real scalar. (INPUT) c Stopping criteria: the relative accuracy of the Ritz value c is considered acceptable if BOUNDS(I) .LE. TOL*ABS(RITZ(I)) c where ABS(RITZ(I)) is the magnitude when RITZ(I) is complex. c DEFAULT = slamch('EPS') (machine precision as computed c by the LAPACK auxiliary subroutine slamch). c c RESID Complex array of length N. (INPUT/OUTPUT) c On INPUT: c If INFO .EQ. 0, a random initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c On OUTPUT: c RESID contains the final residual vector. c c NCV Integer. (INPUT) c Number of columns of the matrix V. NCV must satisfy the two c inequalities 1 <= NCV-NEV and NCV <= N. c This will indicate how many Arnoldi vectors are generated c at each iteration. After the startup phase in which NEV c Arnoldi vectors are generated, the algorithm generates c approximately NCV-NEV Arnoldi vectors at each subsequent update c iteration. Most of the cost in generating each Arnoldi vector is c in the matrix-vector operation OP*x. (See remark 4 below.) c c V Complex array N by NCV. (OUTPUT) c Contains the final set of Arnoldi basis vectors. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling program. c c IPARAM Integer array of length 11. (INPUT/OUTPUT) c IPARAM(1) = ISHIFT: method for selecting the implicit shifts. c The shifts selected at each iteration are used to filter out c the components of the unwanted eigenvector. c ------------------------------------------------------------- c ISHIFT = 0: the shifts are to be provided by the user via c reverse communication. The NCV eigenvalues of c the Hessenberg matrix H are returned in the part c of WORKL array corresponding to RITZ. c ISHIFT = 1: exact shifts with respect to the current c Hessenberg matrix H. This is equivalent to c restarting the iteration from the beginning c after updating the starting vector with a linear c combination of Ritz vectors associated with the c "wanted" eigenvalues. c ISHIFT = 2: other choice of internal shift to be defined. c ------------------------------------------------------------- c c IPARAM(2) = No longer referenced c c IPARAM(3) = MXITER c On INPUT: maximum number of Arnoldi update iterations allowed. c On OUTPUT: actual number of Arnoldi update iterations taken. c c IPARAM(4) = NB: blocksize to be used in the recurrence. c The code currently works only for NB = 1. c c IPARAM(5) = NCONV: number of "converged" Ritz values. c This represents the number of Ritz values that satisfy c the convergence criterion. c c IPARAM(6) = IUPD c No longer referenced. Implicit restarting is ALWAYS used. c c IPARAM(7) = MODE c On INPUT determines what type of eigenproblem is being solved. c Must be 1,2,3; See under \Description of cnaupd for the c four modes available. c c IPARAM(8) = NP c When ido = 3 and the user provides shifts through reverse c communication (IPARAM(1)=0), _naupd returns NP, the number c of shifts the user is to provide. 0 < NP < NCV-NEV. c c IPARAM(9) = NUMOP, IPARAM(10) = NUMOPB, IPARAM(11) = NUMREO, c OUTPUT: NUMOP = total number of OP*x operations, c NUMOPB = total number of B*x operations if BMAT='G', c NUMREO = total number of steps of re-orthogonalization. c c IPNTR Integer array of length 14.

See Remark 5 below. c c Note: IPNTR(9:13) is only referenced by cneupd. See Remark 2 below. c c IPNTR(9): pointer to the NCV RITZ values of the c original system. c IPNTR(10): Not Used c IPNTR(11): pointer to the NCV corresponding error bounds. c IPNTR(12): pointer to the NCV by NCV upper triangular c Schur matrix for H. c IPNTR(13): pointer to the NCV by NCV matrix of eigenvectors c of the upper Hessenberg matrix H. Only referenced by c cneupd if RVEC = .TRUE. See Remark 2 below. c c ------------------------------------------------------------- c c WORKD Complex work array of length 3*N. (REVERSE COMMUNICATION) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration !!!!!!!!!! c See Data Distribution Note below. c c WORKL Complex work array of length LWORKL. (OUTPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. See Data Distribution Note below. c c LWORKL Integer. (INPUT) c LWORKL must be at least 3*NCV**2 + 5*NCV. c c RWORK Real work array of length NCV (WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. c c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal exit. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. IPARAM(5) c returns the number of wanted converged Ritz values. c = 2: No longer an informational error. Deprecated starting c with release 2 of ARPACK. c = 3: No shifts could be applied during a cycle of the c Implicitly restarted Arnoldi iteration. One possibility c is to increase the size of NCV relative to NEV. c See remark 4 below. c = -1: N must be positive. c = -2: NEV must be positive. c = -3: NCV-NEV >= 1 and less than or equal to N. c = -4: The maximum number of Arnoldi update iteration c must be greater than zero. c = -5: WHICH must be one of 'LM', 'SM', 'LR', 'SR', 'LI', 'SI' c = -6: BMAT must be one of 'I' or 'G'. c = -7: Length of private work array is not sufficient. c = -8: Error return from LAPACK eigenvalue calculation; c = -9: Starting vector is zero. c = -10: IPARAM(7) must be 1,2,3. c = -11: IPARAM(7) = 1 and BMAT = 'G' are incompatible. c = -12: IPARAM(1) must be equal to 0 or 1. c = -9999: Could not build an Arnoldi factorization. c User input error highly likely. Please c check actual array dimensions and layout. c IPARAM(5) returns the size of the current Arnoldi c factorization. c c\Remarks c 1. The computed Ritz values are approximate eigenvalues of OP. The c selection of WHICH should be made with this in mind when using c Mode = 3. When operating in Mode = 3 setting WHICH = 'LM' will c compute the NEV eigenvalues of the original problem that are c closest to the shift SIGMA . After convergence, approximate eigenvalues c of the original problem may be obtained with the ARPACK subroutine cneupd. c c 2. If a basis for the invariant subspace corresponding to the converged Ritz c values is needed, the user must call cneupd immediately following c completion of cnaupd. This is new starting with release 2 of ARPACK. c c 3. If M can be factored into a Cholesky factorization M = LL` c then Mode = 2 should not be selected. Instead one should use c Mode = 1 with OP = inv(L)*A*inv(L`). Appropriate triangular c linear systems should be solved with L and L` rather c than computing inverses. After convergence, an approximate c eigenvector z of the original problem is recovered by solving c L`z = x where x is a Ritz vector of OP. c c 4. At present there is no a-priori analysis to guide the selection c of NCV relative to NEV. The only formal requirement is that NCV > NEV + 1. c However, it is recommended that NCV .ge. 2*NEV. If many problems of c the same type are to be solved, one should experiment with increasing c NCV while keeping NEV fixed for a given test problem. This will c usually decrease the required number of OP*x operations but it c also increases the work and storage required to maintain the orthogonal c basis vectors. The optimal "cross-over" with respect to CPU time c is problem dependent and must be determined empirically. c See Chapter 8 of Reference 2 for further information. c c 5. When IPARAM(1) = 0, and IDO = 3, the user needs to provide the c NP = IPARAM(8) complex shifts in locations c WORKL(IPNTR(14)), WORKL(IPNTR(14)+1), ... , WORKL(IPNTR(14)+NP). c Eigenvalues of the current upper Hessenberg matrix are located in c WORKL(IPNTR(6)) through WORKL(IPNTR(6)+NCV-1). They are ordered c according to the order defined by WHICH. The associated Ritz estimates c are located in WORKL(IPNTR(8)), WORKL(IPNTR(8)+1), ... , c WORKL(IPNTR(8)+NCV-1). c c----------------------------------------------------------------------- c c\Data Distribution Note: c c Fortran-D syntax: c ================ c Complex resid(n), v(ldv,ncv), workd(3*n), workl(lworkl) c decompose d1(n), d2(n,ncv) c align resid(i) with d1(i) c align v(i,j) with d2(i,j) c align workd(i) with d1(i) range (1:n) c align workd(i) with d1(i-n) range (n+1:2*n) c align workd(i) with d1(i-2*n) range (2*n+1:3*n) c distribute d1(block), d2(block,:) c replicated workl(lworkl) c c Cray MPP syntax: c =============== c Complex resid(n), v(ldv,ncv), workd(n,3), workl(lworkl) c shared resid(block), v(block,:), workd(block,:) c replicated workl(lworkl) c c CM2/CM5 syntax: c ============== c c----------------------------------------------------------------------- c c include 'ex-nonsym.doc' c c----------------------------------------------------------------------- c c\BeginLib c c\Local variables: c xxxxxx Complex c c\References: c 1.

This is intended to be used to find a few eigenpairs of a c complex linear operator OP with respect to a semi-inner product defined c by a hermitian positive semi-definite real matrix B. B may be the identity c matrix. NOTE: if both OP and B are real, then dsaupd or dnaupd should c be used. c c c The computed approximate eigenvalues are called Ritz values and c the corresponding approximate eigenvectors are called Ritz vectors. c c znaupd is usually called iteratively to solve one of the c following problems: c c Mode 1: A*x = lambda*x. c ===> OP = A and B = I. c c Mode 2: A*x = lambda*M*x, M hermitian positive definite c ===> OP = inv[M]*A and B = M. c ===> (If M can be factored see remark 3 below) c c Mode 3: A*x = lambda*M*x, M hermitian semi-definite c ===> OP = inv[A - sigma*M]*M and B = M. c ===> shift-and-invert mode c If OP*x = amu*x, then lambda = sigma + 1/amu. c c c NOTE: The action of w <- inv[A - sigma*M]*v or w <- inv[M]*v c should be accomplished either by a direct method c using a sparse matrix factorization and solving c c [A - sigma*M]*w = v or M*w = v, c c or through an iterative method for solving these c systems. If an iterative method is used, the c convergence test must be more stringent than c the accuracy requirements for the eigenvalue c approximations. c c\Usage: c call znaupd c ( IDO, BMAT, N, WHICH, NEV, TOL, RESID, NCV, V, LDV, IPARAM, c IPNTR, WORKD, WORKL, LWORKL, RWORK, INFO ) c c\Arguments c IDO Integer. (INPUT/OUTPUT) c Reverse communication flag. IDO must be zero on the first c call to znaupd. IDO will be set internally to c indicate the type of operation to be performed. Control is c then given back to the calling routine which has the c responsibility to carry out the requested operation and call c znaupd with the result. The operand is given in c WORKD(IPNTR(1)), the result must be put in WORKD(IPNTR(2)). c ------------------------------------------------------------- c IDO = 0: first call to the reverse communication interface c IDO = -1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c This is for the initialization phase to force the c starting vector into the range of OP. c IDO = 1: compute Y = OP * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c In mode 3, the vector B * X is already c available in WORKD(ipntr(3)). It does not c need to be recomputed in forming OP * X. c IDO = 2: compute Y = M * X where c IPNTR(1) is the pointer into WORKD for X, c IPNTR(2) is the pointer into WORKD for Y. c IDO = 3: compute and return the shifts in the first c NP locations of WORKL. c IDO = 99: done c ------------------------------------------------------------- c After the initialization phase, when the routine is used in c the "shift-and-invert" mode, the vector M * X is already c available and does not need to be recomputed in forming OP*X. c c BMAT Character*1. (INPUT) c BMAT specifies the type of the matrix B that defines the c semi-inner product for the operator OP. c BMAT = 'I' -> standard eigenvalue problem A*x = lambda*x c BMAT = 'G' -> generalized eigenvalue problem A*x = lambda*M*x c c N Integer. (INPUT) c Dimension of the eigenproblem. c c WHICH Character*2. (INPUT) c 'LM' -> want the NEV eigenvalues of largest magnitude. c 'SM' -> want the NEV eigenvalues of smallest magnitude. c 'LR' -> want the NEV eigenvalues of largest real part. c 'SR' -> want the NEV eigenvalues of smallest real part. c 'LI' -> want the NEV eigenvalues of largest imaginary part. c 'SI' -> want the NEV eigenvalues of smallest imaginary part. c c NEV Integer. (INPUT) c Number of eigenvalues of OP to be computed. 0 < NEV < N-1. c c TOL Double precision scalar. (INPUT) c Stopping criteria: the relative accuracy of the Ritz value c is considered acceptable if BOUNDS(I) .LE. TOL*ABS(RITZ(I)) c where ABS(RITZ(I)) is the magnitude when RITZ(I) is complex. c DEFAULT = dlamch('EPS') (machine precision as computed c by the LAPACK auxiliary subroutine dlamch). c c RESID Complex*16 array of length N. (INPUT/OUTPUT) c On INPUT: c If INFO .EQ. 0, a random initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c On OUTPUT: c RESID contains the final residual vector. c c NCV Integer. (INPUT) c Number of columns of the matrix V. NCV must satisfy the two c inequalities 1 <= NCV-NEV and NCV <= N. c This will indicate how many Arnoldi vectors are generated c at each iteration. After the startup phase in which NEV c Arnoldi vectors are generated, the algorithm generates c approximately NCV-NEV Arnoldi vectors at each subsequent update c iteration. Most of the cost in generating each Arnoldi vector is c in the matrix-vector operation OP*x. (See remark 4 below.) c c V Complex*16 array N by NCV. (OUTPUT) c Contains the final set of Arnoldi basis vectors. c c LDV Integer. (INPUT) c Leading dimension of V exactly as declared in the calling program. c c IPARAM Integer array of length 11. (INPUT/OUTPUT) c IPARAM(1) = ISHIFT: method for selecting the implicit shifts. c The shifts selected at each iteration are used to filter out c the components of the unwanted eigenvector. c ------------------------------------------------------------- c ISHIFT = 0: the shifts are to be provided by the user via c reverse communication. The NCV eigenvalues of c the Hessenberg matrix H are returned in the part c of WORKL array corresponding to RITZ. c ISHIFT = 1: exact shifts with respect to the current c Hessenberg matrix H. This is equivalent to c restarting the iteration from the beginning c after updating the starting vector with a linear c combination of Ritz vectors associated with the c "wanted" eigenvalues. c ISHIFT = 2: other choice of internal shift to be defined. c ------------------------------------------------------------- c c IPARAM(2) = No longer referenced c c IPARAM(3) = MXITER c On INPUT: maximum number of Arnoldi update iterations allowed. c On OUTPUT: actual number of Arnoldi update iterations taken. c c IPARAM(4) = NB: blocksize to be used in the recurrence. c The code currently works only for NB = 1. c c IPARAM(5) = NCONV: number of "converged" Ritz values. c This represents the number of Ritz values that satisfy c the convergence criterion. c c IPARAM(6) = IUPD c No longer referenced. Implicit restarting is ALWAYS used. c c IPARAM(7) = MODE c On INPUT determines what type of eigenproblem is being solved. c Must be 1,2,3; See under \Description of znaupd for the c four modes available. c c IPARAM(8) = NP c When ido = 3 and the user provides shifts through reverse c communication (IPARAM(1)=0), _naupd returns NP, the number c of shifts the user is to provide. 0 < NP < NCV-NEV. c c IPARAM(9) = NUMOP, IPARAM(10) = NUMOPB, IPARAM(11) = NUMREO, c OUTPUT: NUMOP = total number of OP*x operations, c NUMOPB = total number of B*x operations if BMAT='G', c NUMREO = total number of steps of re-orthogonalization. c c IPNTR Integer array of length 14. (OUTPUT) c Pointer to mark the starting locations in the WORKD and WORKL c arrays for matrices/vectors used by the Arnoldi iteration. c ------------------------------------------------------------- c IPNTR(1): pointer to the current operand vector X in WORKD. c IPNTR(2): pointer to the current result vector Y in WORKD. c IPNTR(3): pointer to the vector B * X in WORKD when used in c the shift-and-invert mode. c IPNTR(4): pointer to the next available location in WORKL c that is untouched by the program. c IPNTR(5): pointer to the NCV by NCV upper Hessenberg c matrix H in WORKL. c IPNTR(6): pointer to the ritz value array RITZ c IPNTR(7): pointer to the (projected) ritz vector array Q c IPNTR(8): pointer to the error BOUNDS array in WORKL. c IPNTR(14): pointer to the NP shifts in WORKL. See Remark 5 below. c c Note: IPNTR(9:13) is only referenced by zneupd. See Remark 2 below. c c IPNTR(9): pointer to the NCV RITZ values of the c original system. c IPNTR(10): Not Used c IPNTR(11): pointer to the NCV corresponding error bounds. c IPNTR(12): pointer to the NCV by NCV upper triangular c Schur matrix for H. c IPNTR(13): pointer to the NCV by NCV matrix of eigenvectors c of the upper Hessenberg matrix H. Only referenced by c zneupd if RVEC = .TRUE. See Remark 2 below. c c ------------------------------------------------------------- c c WORKD Complex*16 work array of length 3*N. (REVERSE COMMUNICATION) c Distributed array to be used in the basic Arnoldi iteration c for reverse communication. The user should not use WORKD c as temporary workspace during the iteration !!!!!!!!!! c See Data Distribution Note below. c c WORKL Complex*16 work array of length LWORKL. (OUTPUT/WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. See Data Distribution Note below. c c LWORKL Integer. (INPUT) c LWORKL must be at least 3*NCV**2 + 5*NCV. c c RWORK Double precision work array of length NCV (WORKSPACE) c Private (replicated) array on each PE or array allocated on c the front end. c c c INFO Integer. (INPUT/OUTPUT) c If INFO .EQ. 0, a randomly initial residual vector is used. c If INFO .NE. 0, RESID contains the initial residual vector, c possibly from a previous run. c Error flag on output. c = 0: Normal exit. c = 1: Maximum number of iterations taken. c All possible eigenvalues of OP has been found. IPARAM(5) c returns the number of wanted converged Ritz values. c = 2: No longer an informational error. Deprecated starting c with release 2 of ARPACK. c = 3: No shifts could be applied during a cycle of the c Implicitly restarted Arnoldi iteration. One possibility c is to increase the size of NCV relative to NEV. c See remark 4 below. c = -1: N must be positive. c = -2: NEV must be positive. c = -3: NCV-NEV >= 1 and less than or equal to N. c = -4: The maximum number of Arnoldi update iteration c must be greater than zero. c = -5: WHICH must be one of 'LM', 'SM', 'LR', 'SR', 'LI', 'SI' c = -6: BMAT must be one of 'I' or 'G'. c = -7: Length of private work array is not sufficient. c = -8: Error return from LAPACK eigenvalue calculation; c = -9: Starting vector is zero. c = -10: IPARAM(7) must be 1,2,3. c = -11: IPARAM(7) = 1 and BMAT = 'G' are incompatible. c = -12: IPARAM(1) must be equal to 0 or 1. c = -9999: Could not build an Arnoldi factorization. c User input error highly likely. Please c check actual array dimensions and layout. c IPARAM(5) returns the size of the current Arnoldi c factorization. c c\Remarks c 1. The computed Ritz values are approximate eigenvalues of OP. The c selection of WHICH should be made with this in mind when using c Mode = 3. When operating in Mode = 3 setting WHICH = 'LM' will c compute the NEV eigenvalues of the original problem that are c closest to the shift SIGMA . After convergence, approximate eigenvalues c of the original problem may be obtained with the ARPACK subroutine zneupd. c c 2. If a basis for the invariant subspace corresponding to the converged Ritz c values is needed, the user must call zneupd immediately following c completion of znaupd. This is new starting with release 2 of ARPACK. c c 3. If M can be factored into a Cholesky factorization M = LL` c then Mode = 2 should not be selected. Instead one should use c Mode = 1 with OP = inv(L)*A*inv(L`). Appropriate triangular c linear systems should be solved with L and L` rather c than computing inverses. After convergence, an approximate c eigenvector z of the original problem is recovered by solving c L`z = x where x is a Ritz vector of OP. c c 4. At present there is no a-priori analysis to guide the selection c of NCV relative to NEV. The only formal requirement is that NCV > NEV + 1. c However, it is recommended that NCV .ge. 2*NEV. If many problems of c the same type are to be solved, one should experiment with increasing c NCV while keeping NEV fixed for a given test problem. This will c usually decrease the required number of OP*x operations but it c also increases the work and storage required to maintain the orthogonal c basis vectors. The optimal "cross-over" with respect to CPU time c is problem dependent and must be determined empirically. c See Chapter 8 of Reference 2 for further information. c c 5. When IPARAM(1) = 0, and IDO = 3, the user needs to provide the c NP = IPARAM(8) complex shifts in locations c WORKL(IPNTR(14)), WORKL(IPNTR(14)+1), ... , WORKL(IPNTR(14)+NP). c Eigenvalues of the current upper Hessenberg matrix are located in c WORKL(IPNTR(6)) through WORKL(IPNTR(6)+NCV-1). They are ordered c according to the order defined by WHICH. The associated Ritz estimates c are located in WORKL(IPNTR(8)), WORKL(IPNTR(8)+1), ... , c WORKL(IPNTR(8)+NCV-1). c c----------------------------------------------------------------------- c c\Data Distribution Note: c c Fortran-D syntax: c ================ c Complex*16 resid(n), v(ldv,ncv), workd(3*n), workl(lworkl) c decompose d1(n), d2(n,ncv) c align resid(i) with d1(i) c align v(i,j) with d2(i,j) c align workd(i) with d1(i) range (1:n) c align workd(i) with d1(i-n) range (n+1:2*n) c align workd(i) with d1(i-2*n) range (2*n+1:3*n) c distribute d1(block), d2(block,:) c replicated workl(lworkl) c c Cray MPP syntax: c =============== c Complex*16 resid(n), v(ldv,ncv), workd(n,3), workl(lworkl) c shared resid(block), v(block,:), workd(block,:) c replicated workl(lworkl) c c CM2/CM5 syntax: c ============== c c----------------------------------------------------------------------- c c include 'ex-nonsym.doc' c c----------------------------------------------------------------------- c c\BeginLib c c\Local variables: c xxxxxx Complex*16 c c\References: c 1.

An orthonormal c basis is always computed. There is an additional storage cost of n*nev c if both are requested (in this case a separate array Z must be supplied). c c The approximate eigenvalues and eigenvectors of A*z = lambda*B*z c are derived from approximate eigenvalues and eigenvectors of c of the linear operator OP prescribed by the MODE selection in the c call to ZNAUPD. ZNAUPD must be called before this routine is called. c These approximate eigenvalues and vectors are commonly called Ritz c values and Ritz vectors respectively. They are referred to as such c in the comments that follow. The computed orthonormal basis for the c invariant subspace corresponding to these Ritz values is referred to as a c Schur basis. c c The definition of OP as well as other terms and the relation of computed c Ritz values and vectors of OP with respect to the given problem c A*z = lambda*B*z may be found in the header of ZNAUPD.
