DDRVSY_AA_2STAGE

DDRVSY_AA_2STAGE

Purpose:

 DDRVSY_AA_2STAGE tests the driver routine DSYSV_AA_2STAGE.

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 (NMAX)

NOUT

          NOUT is INTEGER
          The unit number for output.
