       Purpose:


            ZCHKTZ tests ZTZRZF.

       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.

           NM

                     NM is INTEGER
                     The number of values of M contained in the vector MVAL.

           MVAL

                     MVAL is INTEGER array, dimension (NM)
                     The values of the matrix row dimension M.

           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 column dimension N.

           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.

           A

                     A is COMPLEX*16 array, dimension (MMAX*NMAX)
                     where MMAX is the maximum value of M in MVAL and NMAX is the
                     maximum value of N in NVAL.

           COPYA

                     COPYA is COMPLEX*16 array, dimension (MMAX*NMAX)

           S

                     S is DOUBLE PRECISION array, dimension
                                 (min(MMAX,NMAX))

           TAU

                     TAU is COMPLEX*16 array, dimension (MMAX)

           WORK

                     WORK is COMPLEX*16 array, dimension
                                 (MMAX*NMAX + 4*NMAX + MMAX)

           RWORK

                     RWORK is DOUBLE PRECISION array, dimension (2*NMAX)

           NOUT

                     NOUT is INTEGER
                     The unit number for output.
