SDRVGB
Purpose:
!> !> SDRVGB tests the driver routines SGBSV and -SVX. !>
Parameters
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. !>
NN
!> NN is INTEGER !> The number of values of N contained in the vector NVAL. !>
NVAL
!> NVAL is INTEGER array, dimension (NN) !> The values of the matrix column dimension N. !>
NRHS
!> NRHS is INTEGER !> The number of right hand side vectors to be generated for !> each linear system. !>
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. !>
TSTERR
!> TSTERR is LOGICAL !> Flag that indicates whether error exits are to be tested. !>
A
!> A is REAL array, dimension (LA) !>
LA
!> LA is INTEGER !> The length of the array A. LA >= (2*NMAX-1)*NMAX !> where NMAX is the largest entry in NVAL. !>
AFB
!> AFB is REAL array, dimension (LAFB) !>
LAFB
!> LAFB is INTEGER !> The length of the array AFB. LAFB >= (3*NMAX-2)*NMAX !> where NMAX is the largest entry in NVAL. !>
ASAV
!> ASAV is REAL array, dimension (LA) !>
B
!> B is REAL array, dimension (NMAX*NRHS) !>
BSAV
!> BSAV is REAL array, dimension (NMAX*NRHS) !>
X
!> X is REAL array, dimension (NMAX*NRHS) !>
XACT
!> XACT is REAL array, dimension (NMAX*NRHS) !>
S
!> S is REAL array, dimension (2*NMAX) !>
WORK
!> WORK is REAL array, dimension !> (NMAX*max(3,NRHS,NMAX)) !>
RWORK
!> RWORK is REAL array, dimension !> (NMAX+2*NRHS) !>
IWORK
!> IWORK is INTEGER array, dimension (2*NMAX) !>
NOUT
!> NOUT is INTEGER !> The unit number for output. !>
