ZCHKPT

Purpose:
 ZCHKPT tests ZPTTRF, -TRS, -RFS, and -CON
Parameters
[in]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.
[in]NN
          NN is INTEGER
          The number of values of N contained in the vector NVAL.
[in]NVAL
          NVAL is INTEGER array, dimension (NN)
          The values of the matrix dimension N.
[in]NNS
          NNS is INTEGER
          The number of values of NRHS contained in the vector NSVAL.
[in]NSVAL
          NSVAL is INTEGER array, dimension (NNS)
          The values of the number of right hand sides NRHS.
[in]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.
[in]TSTERR
          TSTERR is LOGICAL
          Flag that indicates whether error exits are to be tested.
[out]A
          A is COMPLEX*16 array, dimension (NMAX*2)
[out]D
          D is DOUBLE PRECISION array, dimension (NMAX*2)
[out]E
          E is COMPLEX*16 array, dimension (NMAX*2)
[out]B
          B is COMPLEX*16 array, dimension (NMAX*NSMAX)
          where NSMAX is the largest entry in NSVAL.
[out]X
          X is COMPLEX*16 array, dimension (NMAX*NSMAX)
[out]XACT
          XACT is COMPLEX*16 array, dimension (NMAX*NSMAX)
[out]WORK
          WORK is COMPLEX*16 array, dimension
                      (NMAX*max(3,NSMAX))
[out]RWORK
          RWORK is DOUBLE PRECISION array, dimension
                      (max(NMAX,2*NSMAX))
[in]NOUT
          NOUT is INTEGER
          The unit number for output.
