TESTING/EIG/zckgsv.f(3) Library Functions Manual TESTING/EIG/zckgsv.f(3) NAME TESTING/EIG/zckgsv.f SYNOPSIS Functions/Subroutines subroutine zckgsv (nm, mval, pval, nval, nmats, iseed, thresh, nmax, a, af, b, bf, u, v, q, alpha, beta, r, iwork, work, rwork, nin, nout, info) ZCKGSV Function/Subroutine Documentation subroutine zckgsv (integer nm, integer, dimension( * ) mval, integer, dimension( * ) pval, integer, dimension( * ) nval, integer nmats, integer, dimension( 4 ) iseed, double precision thresh, integer nmax, complex*16, dimension( * ) a, complex*16, dimension( * ) af, complex*16, dimension( * ) b, complex*16, dimension( * ) bf, complex*16, dimension( * ) u, complex*16, dimension( * ) v, complex*16, dimension( * ) q, double precision, dimension( * ) alpha, double precision, dimension( * ) beta, complex*16, dimension( * ) r, integer, dimension( * ) iwork, complex*16, dimension( * ) work, double precision, dimension( * ) rwork, integer nin, integer nout, integer info) ZCKGSV Purpose: ZCKGSV tests ZGGSVD: the GSVD for M-by-N matrix A and P-by-N matrix B. Parameters NM NM is INTEGER The number of values of M contained in the vector MVAL. MVAL MVAL is INTEGER array, dimension (NM) The values of the matrix row dimension M. PVAL PVAL is INTEGER array, dimension (NP) The values of the matrix row dimension P. NVAL NVAL is INTEGER array, dimension (NN) The values of the matrix column dimension N. NMATS NMATS is 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 ISEED is 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 THRESH is 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 NMAX is INTEGER The maximum value permitted for M or N, used in dimensioning the work arrays. A A is COMPLEX*16 array, dimension (NMAX*NMAX) AF AF is COMPLEX*16 array, dimension (NMAX*NMAX) B B is COMPLEX*16 array, dimension (NMAX*NMAX) BF BF is COMPLEX*16 array, dimension (NMAX*NMAX) U U is COMPLEX*16 array, dimension (NMAX*NMAX) V V is COMPLEX*16 array, dimension (NMAX*NMAX) Q Q is COMPLEX*16 array, dimension (NMAX*NMAX) ALPHA ALPHA is DOUBLE PRECISION array, dimension (NMAX) BETA BETA is DOUBLE PRECISION array, dimension (NMAX) R R is COMPLEX*16 array, dimension (NMAX*NMAX) IWORK IWORK is INTEGER array, dimension (NMAX) WORK WORK is COMPLEX*16 array, dimension (NMAX*NMAX) RWORK RWORK is DOUBLE PRECISION array, dimension (NMAX) NIN NIN is INTEGER The unit number for input. NOUT NOUT is INTEGER The unit number for output. INFO INFO is INTEGER = 0 : successful exit > 0 : If ZLATMS returns an error code, the absolute value of it is returned.
