DDRVPO

Purpose:

     DDRVPO tests the driver routines DPOSV 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 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)

    ASAV

              ASAV is DOUBLE PRECISION array, dimension (NMAX*NMAX)

    B

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

    BSAV

              BSAV 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)

    S

              S is DOUBLE PRECISION array, dimension (NMAX)

    WORK

              WORK is DOUBLE PRECISION array, dimension
                          (NMAX*max(3,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.
