November 2006 Purpose ======= DCKGSV tests DGGSVD: the GSVD for M-by-N matrix A and P-by-N matrix B. Arguments ========= NM (input) INTEGER The number of values of M contained in the vector MVAL. MVAL (input) INTEGER array, dimension (NM) The values of the matrix row dimension M. PVAL (input) INTEGER array, dimension (NP) The values of the matrix row dimension P. NVAL (input) INTEGER array, dimension (NN) The values of the matrix column dimension N. NMATS (input) INTEGER The number of matrix types to be tested for each combination of matrix dimensions. If NMATS >= NTYPES (the maximum number of matrix types), then all the different types are generated for testing. If NMATS < NTYPES, another input line is read to get the numbers of the matrix types to be used. ISEED (input/output) INTEGER array, dimension (4) On entry, the seed of the random number generator. The array elements should be between 0 and 4095, otherwise they will be reduced mod 4096, and ISEED(4) must be odd. On exit, the next seed in the random number sequence after all the test matrices have been generated. THRESH (input) DOUBLE PRECISION The threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0. NMAX (input) INTEGER The maximum value permitted for M or N, used in dimensioning the work arrays. A (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) AF (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) B (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) BF (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) U (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) V (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) Q (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) ALPHA (workspace) DOUBLE PRECISION array, dimension (NMAX) BETA (workspace) DOUBLE PRECISION array, dimension (NMAX) R (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) IWORK (workspace) INTEGER array, dimension (NMAX) WORK (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX) RWORK (workspace) DOUBLE PRECISION array, dimension (NMAX) NIN (input) INTEGER The unit number for input. NOUT (input) INTEGER The unit number for output. INFO (output) INTEGER = 0 : successful exit > 0 : If DLATMS returns an error code, the absolute value of it is returned. ===================================================================== Initialize constants and the random number seed.
