Purpose
=======
DCHKQL tests DGEQLF, DORGQL and DORMQL.
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) DOUBLE PRECISION array, dimension (NMAX*NMAX)
AF (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)
AQ (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)
AL (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)
AC (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)
B (workspace) DOUBLE PRECISION array, dimension (NMAX*NRHS)
X (workspace) DOUBLE PRECISION array, dimension (NMAX*NRHS)
XACT (workspace) DOUBLE PRECISION array, dimension (NMAX*NRHS)
TAU (workspace) DOUBLE PRECISION array, dimension (NMAX)
WORK (workspace) DOUBLE PRECISION 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.
