Purpose
ZDRVGB tests the driver routines ZGBSV and -SVX.
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 column dimension N.
|
| 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.
|
| A |
(workspace) COMPLEX*16 array, dimension (LA)
|
| LA |
(input) INTEGER
The length of the array A. LA >= (2*NMAX-1)*NMAX
where NMAX is the largest entry in NVAL. |
| AFB |
(workspace) COMPLEX*16 array, dimension (LAFB)
|
| LAFB |
(input) INTEGER
The length of the array AFB. LAFB >= (3*NMAX-2)*NMAX
where NMAX is the largest entry in NVAL. |
| ASAV |
(workspace) COMPLEX*16 array, dimension (LA)
|
| B |
(workspace) COMPLEX*16 array, dimension (NMAX*NRHS)
|
| BSAV |
(workspace) COMPLEX*16 array, dimension (NMAX*NRHS)
|
| X |
(workspace) COMPLEX*16 array, dimension (NMAX*NRHS)
|
| XACT |
(workspace) COMPLEX*16 array, dimension (NMAX*NRHS)
|
| S |
(workspace) DOUBLE PRECISION array, dimension (2*NMAX)
|
| WORK |
(workspace) COMPLEX*16 array, dimension
(NMAX*max(3,NRHS,NMAX))
|
| RWORK |
(workspace) DOUBLE PRECISION array, dimension
(max(NMAX,2*NRHS))
|
| IWORK |
(workspace) INTEGER array, dimension (NMAX)
|
| NOUT |
(input) INTEGER
The unit number for output.
