ZCKGQR
Purpose:
ZCKGQR tests ZGGQRF: GQR factorization for N-by-M matrix A and N-by-P matrix B, ZGGRQF: GRQ factorization 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(column) dimension M.
NP
NP is INTEGER The number of values of P contained in the vector PVAL.
PVAL
PVAL is INTEGER array, dimension (NP) The values of the matrix row(column) dimension P.
NN
NN is INTEGER The number of values of N contained in the vector NVAL.
NVAL
NVAL is INTEGER array, dimension (NN) The values of the matrix column(row) 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)
AQ
AQ is COMPLEX*16 array, dimension (NMAX*NMAX)
AR
AR is COMPLEX*16 array, dimension (NMAX*NMAX)
TAUA
TAUA is COMPLEX*16 array, dimension (NMAX)
B
B is COMPLEX*16 array, dimension (NMAX*NMAX)
BF
BF is COMPLEX*16 array, dimension (NMAX*NMAX)
BZ
BZ is COMPLEX*16 array, dimension (NMAX*NMAX)
BT
BT is COMPLEX*16 array, dimension (NMAX*NMAX)
BWK
BWK is COMPLEX*16 array, dimension (NMAX*NMAX)
TAUB
TAUB is COMPLEX*16 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.
