SCHKPO
SCHKPO tests SPOTRF, -TRI, -TRS, -RFS, and -CON
| [in] | 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. |
| [in] | NN | NN is INTEGER
The number of values of N contained in the vector NVAL. |
| [in] | NVAL | NVAL is INTEGER array, dimension (NN)
The values of the matrix dimension N. |
| [in] | NNB | NNB is INTEGER
The number of values of NB contained in the vector NBVAL. |
| [in] | NBVAL | NBVAL is INTEGER array, dimension (NNB)
The values of the blocksize NB. |
| [in] | NNS | NNS is INTEGER
The number of values of NRHS contained in the vector NSVAL. |
| [in] | NSVAL | NSVAL is INTEGER array, dimension (NNS)
The values of the number of right hand sides NRHS. |
| [in] | THRESH | THRESH is REAL
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. |
| [in] | TSTERR | TSTERR is LOGICAL
Flag that indicates whether error exits are to be tested. |
| [in] | NMAX | NMAX is INTEGER
The maximum value permitted for N, used in dimensioning the
work arrays. |
| [out] | A | A is REAL array, dimension (NMAX*NMAX) |
| [out] | AFAC | AFAC is REAL array, dimension (NMAX*NMAX) |
| [out] | AINV | AINV is REAL array, dimension (NMAX*NMAX) |
| [out] | B | B is REAL array, dimension (NMAX*NSMAX)
where NSMAX is the largest entry in NSVAL. |
| [out] | X | X is REAL array, dimension (NMAX*NSMAX) |
| [out] | XACT | XACT is REAL array, dimension (NMAX*NSMAX) |
| [out] | WORK | WORK is REAL array, dimension
(NMAX*max(3,NSMAX)) |
| [out] | RWORK | RWORK is REAL array, dimension
(max(NMAX,2*NSMAX)) |
| [out] | IWORK | IWORK is INTEGER array, dimension (NMAX) |
| [in] | NOUT | NOUT is INTEGER
The unit number for output. |
