CCKGQR
Purpose:
!> !> CCKGQR tests !> CGGQRF: GQR factorization for N-by-M matrix A and N-by-P matrix B, !> CGGRQF: 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 REAL !> 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 array, dimension (NMAX*NMAX) !>
AF
!> AF is COMPLEX array, dimension (NMAX*NMAX) !>
AQ
!> AQ is COMPLEX array, dimension (NMAX*NMAX) !>
AR
!> AR is COMPLEX array, dimension (NMAX*NMAX) !>
TAUA
!> TAUA is COMPLEX array, dimension (NMAX) !>
B
!> B is COMPLEX array, dimension (NMAX*NMAX) !>
BF
!> BF is COMPLEX array, dimension (NMAX*NMAX) !>
BZ
!> BZ is COMPLEX array, dimension (NMAX*NMAX) !>
BT
!> BT is COMPLEX array, dimension (NMAX*NMAX) !>
BWK
!> BWK is COMPLEX array, dimension (NMAX*NMAX) !>
TAUB
!> TAUB is COMPLEX array, dimension (NMAX) !>
WORK
!> WORK is COMPLEX array, dimension (NMAX*NMAX) !>
RWORK
!> RWORK is REAL 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 CLATMS returns an error code, the absolute value !> of it is returned. !>
