DDRVAC tests DSPOSV.

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 N contained in the vector MVAL.

MVAL

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

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 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)

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))

NOUT

          NOUT is INTEGER
          The unit number for output.
