DCHKGB
DCHKGB tests DGBTRF, -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] | NM | NM is INTEGER
The number of values of M contained in the vector MVAL. |
| [in] | MVAL | MVAL is INTEGER array, dimension (NM)
The values of the matrix row dimension M. |
| [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 column 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 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. |
| [in] | TSTERR | TSTERR is LOGICAL
Flag that indicates whether error exits are to be tested. |
| [out] | A | A is DOUBLE PRECISION array, dimension (LA) |
| [in] | LA | LA is INTEGER
The length of the array A. LA >= (KLMAX+KUMAX+1)*NMAX
where KLMAX is the largest entry in the local array KLVAL,
KUMAX is the largest entry in the local array KUVAL and
NMAX is the largest entry in the input array NVAL. |
| [out] | AFAC | AFAC is DOUBLE PRECISION array, dimension (LAFAC) |
| [in] | LAFAC | LAFAC is INTEGER
The length of the array AFAC. LAFAC >= (2*KLMAX+KUMAX+1)*NMAX
where KLMAX is the largest entry in the local array KLVAL,
KUMAX is the largest entry in the local array KUVAL and
NMAX is the largest entry in the input array NVAL. |
| [out] | B | B is DOUBLE PRECISION array, dimension (NMAX*NSMAX)
where NSMAX is the largest entry in NSVAL. |
| [out] | X | X is DOUBLE PRECISION array, dimension (NMAX*NSMAX) |
| [out] | XACT | XACT is DOUBLE PRECISION array, dimension (NMAX*NSMAX) |
| [out] | WORK | WORK is DOUBLE PRECISION array, dimension
(NMAX*max(3,NSMAX,NMAX)) |
| [out] | RWORK | RWORK is DOUBLE PRECISION array, dimension
(NMAX+2*NSMAX) |
| [out] | IWORK | IWORK is INTEGER array, dimension (2*NMAX) |
| [in] | NOUT | NOUT is INTEGER
The unit number for output. |
