subroutine DDRVSY (dotype, nn, nval, nrhs, thresh, tsterr, nmax, a, afac, ainv, b, x, xact, work, rwork, iwork, nout)
DDRVSYX

Function/Subroutine Documentation

subroutine DDRVSY (logical, dimension( * ) dotype, integer nn, integer, dimension( * ) nval, integer nrhs, double precision thresh, logical tsterr, integer nmax, double precision, dimension( * ) a, double precision, dimension( * ) afac, double precision, dimension( * ) ainv, double precision, dimension( * ) b, double precision, dimension( * ) x, double precision, dimension( * ) xact, double precision, dimension( * ) work, double precision, dimension( * ) rwork, integer, dimension( * ) iwork, integer nout)

DDRVSYX

Purpose:

!>
!> DDRVSY tests the driver routines DSYSV, -SVX, and -SVXX.
!>
!> Note that this file is used only when the XBLAS are available,
!> otherwise ddrvsy.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 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

!>          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 DOUBLE PRECISION array, dimension (NMAX*NMAX)
!>

AFAC

!>          AFAC is DOUBLE PRECISION array, dimension (NMAX*NMAX)
!>

AINV

!>          AINV is DOUBLE PRECISION array, dimension (NMAX*NMAX)
!>

B

!>          B is DOUBLE PRECISION array, dimension (NMAX*NRHS)
!>

X

!>          X is DOUBLE PRECISION array, dimension (NMAX*NRHS)
!>

XACT

!>          XACT is DOUBLE PRECISION array, dimension (NMAX*NRHS)
!>

WORK

!>          WORK is DOUBLE PRECISION array, dimension
!>                      (NMAX*max(2,NRHS))
!>

RWORK

!>          RWORK is DOUBLE PRECISION array, dimension (NMAX+2*NRHS)
!>

IWORK

!>          IWORK is INTEGER array, dimension (2*NMAX)
!>

NOUT

!>          NOUT is INTEGER
!>          The unit number for output.
