ZCHKTZ tests ZTZRZF.

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.
