Purpose:



 DDRVAC tests DSPOSV.

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 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 is DOUBLE PRECISION array, dimension (NMAX*NMAX)

AFAC



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



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



          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.
