DDRVAB

Purpose:

     DDRVAB tests DSGESV

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.

    NM

              NM is INTEGER
              The number of values of M contained in the vector MVAL.

    MVAL

              MVAL is INTEGER array, dimension (NM)
              The values of the matrix row dimension M.

    NNS

              NNS is INTEGER
              The number of values of NRHS contained in the vector NSVAL.

    NSVAL

              NSVAL is INTEGER array, dimension (NNS)
              The values of the number of right hand sides NRHS.

    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.

    NMAX

              NMAX is INTEGER
              The maximum value permitted for M or 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)

    B

              B is DOUBLE PRECISION array, dimension (NMAX*NSMAX)
              where NSMAX is the largest entry in NSVAL.

    X

              X is DOUBLE PRECISION array, dimension (NMAX*NSMAX)

    WORK

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

    RWORK

              RWORK is DOUBLE PRECISION array, dimension
                          (max(2*NMAX,2*NSMAX+NWORK))

    SWORK

              SWORK is REAL array, dimension
                          (NMAX*(NSMAX+NMAX))

    IWORK

              IWORK is INTEGER array, dimension
                          NMAX

    NOUT

              NOUT is INTEGER
              The unit number for output.
