SCHKPO

Purpose:

     SCHKPO tests SPOTRF, -TRI, -TRS, -RFS, and -CON

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 blocksize NB.

    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 REAL
              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 REAL array, dimension (NMAX*NMAX)

    AFAC

              AFAC is REAL array, dimension (NMAX*NMAX)

    AINV

              AINV is REAL array, dimension (NMAX*NMAX)

    B

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

    X

              X is REAL array, dimension (NMAX*NSMAX)

    XACT

              XACT is REAL array, dimension (NMAX*NSMAX)

    WORK

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

    RWORK

              RWORK is REAL array, dimension
                          (max(NMAX,2*NSMAX))

    IWORK

              IWORK is INTEGER array, dimension (NMAX)

    NOUT

              NOUT is INTEGER
              The unit number for output.
