SDRVSYX
Purpose:
!> !> SDRVSY tests the driver routines SSYSV, -SVX, and -SVXX !> !> Note that this file is used only when the XBLAS are available, !> otherwise sdrvsy.f defines this subroutine. !>
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 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. !>
NMAX
!> NMAX is INTEGER !> The maximum value permitted for N, used in dimensioning the !> work arrays. !>
A
!> A is REAL array, dimension (NMAX*NMAX) !>
AFAC
!> AFAC is REAL array, dimension (NMAX*NMAX) !>
AINV
!> AINV is REAL array, dimension (NMAX*NMAX) !>
B
!> B is REAL array, dimension (NMAX*NRHS) !>
X
!> X is REAL array, dimension (NMAX*NRHS) !>
XACT
!> XACT is REAL array, dimension (NMAX*NRHS) !>
WORK
!> WORK is REAL array, dimension !> (NMAX*max(2,NRHS)) !>
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. !>
