Purpose
DCHKSY tests DSYTRF, -TRI2, -TRS, -TRS2, -RFS, and -CON.
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. |
| 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 dimension N.
|
| NNB |
(input) INTEGER
The number of values of NB contained in the vector NBVAL.
|
| NBVAL |
(input) INTEGER array, dimension (NBVAL)
The values of the blocksize NB.
|
| NNS |
(input) INTEGER
The number of values of NRHS contained in the vector NSVAL.
|
| NSVAL |
(input) INTEGER array, dimension (NNS)
The values of the number of right hand sides NRHS.
|
| 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 N, used in dimensioning the
work arrays. |
| A |
(workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)
|
| AFAC |
(workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)
|
| AINV |
(workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)
|
| B |
(workspace) DOUBLE PRECISION array, dimension (NMAX*NSMAX)
where NSMAX is the largest entry in NSVAL.
|
| X |
(workspace) DOUBLE PRECISION array, dimension (NMAX*NSMAX)
|
| XACT |
(workspace) DOUBLE PRECISION array, dimension (NMAX*NSMAX)
|
| WORK |
(workspace) DOUBLE PRECISION array, dimension
(NMAX*max(3,NSMAX))
|
| RWORK |
(workspace) DOUBLE PRECISION array, dimension
(max(NMAX,2*NSMAX))
|
| IWORK |
(workspace) INTEGER array, dimension (2*NMAX)
|
| NOUT |
(input) INTEGER
The unit number for output.
