Purpose
DCHKQ3 tests DGEQP3.
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.
|
| 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. |
| A |
(workspace) DOUBLE PRECISION array, dimension (MMAX*NMAX)
where MMAX is the maximum value of M in MVAL and NMAX is the
maximum value of N in NVAL. |
| COPYA |
(workspace) DOUBLE PRECISION array, dimension (MMAX*NMAX)
|
| S |
(workspace) DOUBLE PRECISION array, dimension
(min(MMAX,NMAX))
|
| COPYS |
(workspace) DOUBLE PRECISION array, dimension
(min(MMAX,NMAX))
|
| TAU |
(workspace) DOUBLE PRECISION array, dimension (MMAX)
|
| WORK |
(workspace) DOUBLE PRECISION array, dimension
(MMAX*NMAX + 4*NMAX + MMAX)
|
| IWORK |
(workspace) INTEGER array, dimension (2*NMAX)
|
| NOUT |
(input) INTEGER
The unit number for output.
