/*  -- LAPACK test routine (version 3.1) -- */
/*     Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd.. */
/*     November 2006 */

/*     .. 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 */

/*  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)) */
