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 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 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.
