ZCHKPP

Purpose:



 ZCHKPP tests ZPPTRF, -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 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.

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.

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 COMPLEX*16 array, dimension


                      (NMAX*(NMAX+1)/2)

AFAC



          AFAC is COMPLEX*16 array, dimension


                      (NMAX*(NMAX+1)/2)

AINV



          AINV is COMPLEX*16 array, dimension


                      (NMAX*(NMAX+1)/2)



          B is COMPLEX*16 array, dimension (NMAX*NSMAX)


          where NSMAX is the largest entry in NSVAL.



          X is COMPLEX*16 array, dimension (NMAX*NSMAX)

XACT



          XACT is COMPLEX*16 array, dimension (NMAX*NSMAX)

WORK



          WORK is COMPLEX*16 array, dimension


                      (NMAX*max(3,NSMAX))

RWORK



          RWORK is DOUBLE PRECISION array, dimension


                      (max(NMAX,2*NSMAX))

NOUT



          NOUT is INTEGER


          The unit number for output.
