CCHKTZ

Purpose:

     CCHKTZ tests CTZRZF.

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 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.

    A

              A is COMPLEX 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 array, dimension (MMAX*NMAX)

    S

              S is REAL array, dimension
                          (min(MMAX,NMAX))

    TAU

              TAU is COMPLEX array, dimension (MMAX)

    WORK

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

    RWORK

              RWORK is REAL array, dimension (2*NMAX)

    NOUT

              NOUT is INTEGER
              The unit number for output.
