ZCHKRQ
Purpose:
!> !> ZCHKRQ tests ZGERQF, ZUNGRQ and ZUNMRQ. !>
Parameters
DOTYPE
!> DOTYPE is LOGICAL array, dimension (NTYPES) !> The matrix types to be used for testing. Matrices of type j !> (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = !> .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. !>
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. !>
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 dimension N. !>
NNB
!> NNB is INTEGER !> The number of values of NB and NX contained in the !> vectors NBVAL and NXVAL. The blocking parameters are used !> in pairs (NB,NX). !>
NBVAL
!> NBVAL is INTEGER array, dimension (NNB) !> The values of the blocksize NB. !>
NXVAL
!> NXVAL is INTEGER array, dimension (NNB) !> The values of the crossover point NX. !>
NRHS
!> NRHS is INTEGER !> The number of right hand side vectors to be generated for !> each linear system. !>
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. !>
TSTERR
!> TSTERR is LOGICAL !> Flag that indicates whether error exits are to be tested. !>
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) !>
AC
!> AC is COMPLEX*16 array, dimension (NMAX*NMAX) !>
B
!> B is COMPLEX*16 array, dimension (NMAX*NRHS) !>
X
!> X is COMPLEX*16 array, dimension (NMAX*NRHS) !>
XACT
!> XACT is COMPLEX*16 array, dimension (NMAX*NRHS) !>
TAU
!> TAU is COMPLEX*16 array, dimension (NMAX) !>
WORK
!> WORK is COMPLEX*16 array, dimension (NMAX*NMAX) !>
RWORK
!> RWORK is DOUBLE PRECISION array, dimension (NMAX) !>
IWORK
!> IWORK is INTEGER array, dimension (NMAX) !>
NOUT
!> NOUT is INTEGER !> The unit number for output. !>
