DDRVGB
DDRVGBX
DDRVGB tests the driver routines DGBSV and -SVX.
[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 column dimension N. |
[in] | NRHS | NRHS is INTEGER The number of right hand side vectors to be generated for each linear system. |
[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 >= (2*NMAX-1)*NMAX where NMAX is the largest entry in NVAL. |
[out] | AFB | AFB is DOUBLE PRECISION array, dimension (LAFB) |
[in] | LAFB | LAFB is INTEGER The length of the array AFB. LAFB >= (3*NMAX-2)*NMAX where NMAX is the largest entry in NVAL. |
[out] | ASAV | ASAV is DOUBLE PRECISION array, dimension (LA) |
[out] | B | B is DOUBLE PRECISION array, dimension (NMAX*NRHS) |
[out] | BSAV | BSAV is DOUBLE PRECISION array, dimension (NMAX*NRHS) |
[out] | X | X is DOUBLE PRECISION array, dimension (NMAX*NRHS) |
[out] | XACT | XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS) |
[out] | S | S is DOUBLE PRECISION array, dimension (2*NMAX) |
[out] | WORK | WORK is DOUBLE PRECISION array, dimension (NMAX*max(3,NRHS,NMAX)) |
[out] | RWORK | RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS) |
[out] | IWORK | IWORK is INTEGER array, dimension (2*NMAX) |
[in] | NOUT | NOUT is INTEGER The unit number for output. |
DDRVGB tests the driver routines DGBSV, -SVX, and -SVXX. Note that this file is used only when the XBLAS are available, otherwise ddrvgb.f defines this subroutine.
[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 column dimension N. |
[in] | NRHS | NRHS is INTEGER The number of right hand side vectors to be generated for each linear system. |
[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. |
