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 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 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 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 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.
