/* Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd.. */

/* .. Scalar Arguments .. */
/* .. */
/* .. Array Arguments .. */
/* .. */
/* Purpose */
/* ======= */
/* CDRVBD checks the singular value decomposition (SVD) driver CGESVD */
/* and CGESDD. */
/* CGESVD and CGESDD factors A = U diag(S) VT, where U and VT are */
/* unitary and diag(S) is diagonal with the entries of the array S on */
/* its diagonal. The entries of S are the singular values, nonnegative */
/* and stored in decreasing order. U and VT can be optionally not */
/* computed, overwritten on A, or computed partially. */
/* A is M by N. Let MNMIN = min( M, N ). S has dimension MNMIN. */
/* U can be M by M or M by MNMIN. VT can be N by N or MNMIN by N. */
/* When CDRVBD is called, a number of matrix "sizes" (M's and N's) */
/* and a number of matrix "types" are specified. For each size (M,N) */
/* and each type of matrix, and for the minimal workspace as well as */
/* workspace adequate to permit blocking, an M x N matrix "A" will be */
/* generated and used to test the SVD routines. For each matrix, A will */
/* be factored as A = U diag(S) VT and the following 12 tests computed: */
/* Test for CGESVD: */
/* (1) | A - U diag(S) VT | / ( |A| max(M,N) ulp ) */
/* (2) | I - U'U | / ( M ulp ) */
/* (3) | I - VT VT' | / ( N ulp ) */
/* (4) S contains MNMIN nonnegative values in decreasing order. */
/* (Return 0 if true, 1/ULP if false.) */
/* (5) | U - Upartial | / ( M ulp ) where Upartial is a partially */
/* computed U. */
/* (6) | VT - VTpartial | / ( N ulp ) where VTpartial is a partially */
/* computed VT. */
/* (7) | S - Spartial | / ( MNMIN ulp |S| ) where Spartial is the */
/* vector of singular values from the partial SVD */
/* Test for CGESDD: */
/* (1) | A - U diag(S) VT | / ( |A| max(M,N) ulp ) */
/* (2) | I - U'U | / ( M ulp ) */
/* (3) | I - VT VT' | / ( N ulp ) */
/* (4) S contains MNMIN nonnegative values in decreasing order. */
/* (Return 0 if true, 1/ULP if false.) */
/* (5) | U - Upartial | / ( M ulp ) where Upartial is a partially */
/* computed U. */
/* (6) | VT - VTpartial | / ( N ulp ) where VTpartial is a partially */
/* computed VT. */
/* (7) | S - Spartial | / ( MNMIN ulp |S| ) where Spartial is the */
/* vector of singular values from the partial SVD */
/* The "sizes" are specified by the arrays MM(1:NSIZES) and */
/* NN(1:NSIZES); the value of each element pair (MM(j),NN(j)) */
/* specifies one size. The "types" are specified by a logical array */
/* DOTYPE( 1:NTYPES ); if DOTYPE(j) is .TRUE., then matrix type "j" */
/* will be generated. */
/* Currently, the list of possible types is: */
/* (1) The zero matrix. */
/* (2) The identity matrix. */
/* (3) A matrix of the form U D V, where U and V are unitary and */
/* D has evenly spaced entries 1, ..., ULP with random signs */
/* on the diagonal. */
/* (4) Same as (3), but multiplied by the underflow-threshold / ULP. */
/* (5) Same as (3), but multiplied by the overflow-threshold * ULP. */
/* Arguments */
/* ========== */
/* NSIZES (input) INTEGER */
/* The number of sizes of matrices to use. If it is zero, */
/* CDRVBD does nothing. It must be at least zero. */
/* MM (input) INTEGER array, dimension (NSIZES) */
/* An array containing the matrix "heights" to be used. For */
/* each j=1,...,NSIZES, if MM(j) is zero, then MM(j) and NN(j) */
/* will be ignored. The MM(j) values must be at least zero. */
/* NN (input) INTEGER array, dimension (NSIZES) */
/* An array containing the matrix "widths" to be used. For */
/* each j=1,...,NSIZES, if NN(j) is zero, then MM(j) and NN(j) */
/* will be ignored. The NN(j) values must be at least zero. */
/* NTYPES (input) INTEGER */
/* The number of elements in DOTYPE. If it is zero, CDRVBD */
/* does nothing. It must be at least zero. If it is MAXTYP+1 */
/* and NSIZES is 1, then an additional type, MAXTYP+1 is */
/* defined, which is to use whatever matrices are in A and B. */
/* This is only useful if DOTYPE(1:MAXTYP) is .FALSE. and */
/* DOTYPE(MAXTYP+1) is .TRUE. . */
/* DOTYPE (input) LOGICAL array, dimension (NTYPES) */
/* If DOTYPE(j) is .TRUE., then for each size (m,n), a matrix */
/* of type j will be generated. If NTYPES is smaller than the */
/* maximum number of types defined (PARAMETER MAXTYP), then */
/* types NTYPES+1 through MAXTYP will not be generated. If */
/* NTYPES is larger than MAXTYP, DOTYPE(MAXTYP+1) through */
/* DOTYPE(NTYPES) will be ignored. */
/* ISEED (input/output) INTEGER array, dimension (4) */
/* On entry ISEED specifies the seed of the random number */
/* generator. The array elements should be between 0 and 4095; */
/* if not they will be reduced mod 4096. Also, ISEED(4) must */
/* be odd. The random number generator uses a linear */
/* congruential sequence limited to small integers, and so */
/* should produce machine independent random numbers. The */
/* values of ISEED are changed on exit, and can be used in the */
/* next call to CDRVBD to continue the same random number */
/* sequence. */
/* THRESH (input) REAL */
/* A test will count as "failed" if the "error", computed as */
/* described above, exceeds THRESH. Note that the error */
/* is scaled to be O(1), so THRESH should be a reasonably */
/* small multiple of 1, e.g., 10 or 100. In particular, */
/* it should not depend on the precision (single vs. double) */
/* or the size of the matrix. It must be at least zero. */
/* NOUNIT (input) INTEGER */
/* The FORTRAN unit number for printing out error messages */
/* (e.g., if a routine returns IINFO not equal to 0.) */
/* A (output) COMPLEX array, dimension (LDA,max(NN)) */
/* Used to hold the matrix whose singular values are to be */
/* computed. On exit, A contains the last matrix actually */
/* used. */
/* LDA (input) INTEGER */
/* The leading dimension of A. It must be at */
/* least 1 and at least max( MM ). */
/* U (output) COMPLEX array, dimension (LDU,max(MM)) */
/* Used to hold the computed matrix of right singular vectors. */
/* On exit, U contains the last such vectors actually computed. */
/* LDU (input) INTEGER */
/* The leading dimension of U. It must be at */
/* least 1 and at least max( MM ). */
/* VT (output) COMPLEX array, dimension (LDVT,max(NN)) */
/* Used to hold the computed matrix of left singular vectors. */
/* On exit, VT contains the last such vectors actually computed. */
/* LDVT (input) INTEGER */
/* The leading dimension of VT. It must be at */
/* least 1 and at least max( NN ). */
/* ASAV (output) COMPLEX array, dimension (LDA,max(NN)) */
/* Used to hold a different copy of the matrix whose singular */
/* values are to be computed. On exit, A contains the last */
/* matrix actually used. */
/* USAV (output) COMPLEX array, dimension (LDU,max(MM)) */
/* Used to hold a different copy of the computed matrix of */
/* right singular vectors. On exit, USAV contains the last such */
/* vectors actually computed. */
/* VTSAV (output) COMPLEX array, dimension (LDVT,max(NN)) */
/* Used to hold a different copy of the computed matrix of */
/* left singular vectors. On exit, VTSAV contains the last such */
/* vectors actually computed. */
/* S (output) REAL array, dimension (max(min(MM,NN))) */
/* Contains the computed singular values. */
/* SSAV (output) REAL array, dimension (max(min(MM,NN))) */
/* Contains another copy of the computed singular values. */
/* E (output) REAL array, dimension (max(min(MM,NN))) */
/* Workspace for CGESVD. */
/* WORK (workspace) COMPLEX array, dimension (LWORK) */
/* LWORK (input) INTEGER */
/* The number of entries in WORK. This must be at least */
/* MAX(3*MIN(M,N)+MAX(M,N)**2,5*MIN(M,N),3*MAX(M,N)) for all */
/* pairs (M,N)=(MM(j),NN(j)) */
/* RWORK (workspace) REAL array, */
/* dimension ( 5*max(max(MM,NN)) ) */
/* IWORK (workspace) INTEGER array, dimension at least 8*min(M,N) */
/* RESULT (output) REAL array, dimension (7) */
/* The values computed by the 7 tests described above. */
/* The values are currently limited to 1/ULP, to avoid */
/* overflow. */
/* INFO (output) INTEGER */
/* If 0, then everything ran OK. */
/* -1: NSIZES < 0 */
/* -2: Some MM(j) < 0 */
/* -3: Some NN(j) < 0 */
/* -4: NTYPES < 0 */
/* -7: THRESH < 0 */

/* -12: LDU < 1 or LDU < MMAX. */
/* -14: LDVT < 1 or LDVT < NMAX, where NMAX is max( NN(j) ). */
/* -21: LWORK too small. */
