DCHKPS

Purpose:

 DCHKPS tests DPSTRF.

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.

NNB

          NNB is INTEGER
          The number of values of NB contained in the vector NBVAL.

NBVAL

          NBVAL is INTEGER array, dimension (NNB)
          The values of the block size NB.

NRANK

          NRANK is INTEGER
          The number of values of RANK contained in the vector RANKVAL.

RANKVAL

          RANKVAL is INTEGER array, dimension (NBVAL)
          The values of the block size NB.

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)

PERM

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

PIV

          PIV is INTEGER array, dimension (NMAX)

WORK

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

RWORK

          RWORK is DOUBLE PRECISION array, dimension (NMAX)

NOUT

          NOUT is INTEGER
          The unit number for output.
