Purpose
ZCHKQR tests ZGEQRF, ZUNGQR and CUNMQR.
Arguments
DOTYPE |
(input) 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 |
(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.
|
NN |
(input) INTEGER
The number of values of N contained in the vector NVAL.
|
NVAL |
(input) INTEGER array, dimension (NN)
The values of the matrix column dimension N.
|
NNB |
(input) 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 |
(input) INTEGER array, dimension (NNB)
The values of the blocksize NB.
|
NXVAL |
(input) INTEGER array, dimension (NNB)
The values of the crossover point NX.
|
NRHS |
(input) INTEGER
The number of right hand side vectors to be generated for
each linear system. |
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. |
TSTERR |
(input) LOGICAL
Flag that indicates whether error exits are to be tested.
|
NMAX |
(input) INTEGER
The maximum value permitted for M or N, used in dimensioning
the work arrays. |
A |
(workspace) COMPLEX*16 array, dimension (NMAX*NMAX)
|
AF |
(workspace) COMPLEX*16 array, dimension (NMAX*NMAX)
|
AQ |
(workspace) COMPLEX*16 array, dimension (NMAX*NMAX)
|
AR |
(workspace) COMPLEX*16 array, dimension (NMAX*NMAX)
|
AC |

|
B |
(workspace) COMPLEX*16 array, dimension (NMAX*NRHS)
|
X |
(workspace) COMPLEX*16 array, dimension (NMAX*NRHS)
|
XACT |
(workspace) COMPLEX*16 array, dimension (NMAX*NRHS)
|
TAU |
(workspace) COMPLEX*16 array, dimension (NMAX)
|
WORK |
(workspace) COMPLEX*16 array, dimension (NMAX*NMAX)
|
RWORK |
(workspace) DOUBLE PRECISION array, dimension (NMAX)
|
IWORK |
(workspace) INTEGER array, dimension (NMAX)
|
NOUT |
(input) INTEGER
The unit number for output.
