       Purpose:


            ZCHKTR tests ZTRTRI, -TRS, -RFS, and -CON, and ZLATRS(3)

       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.

           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.

           NNB

                     NNB is INTEGER
                     The number of values of NB contained in the vector NBVAL.

           NBVAL

                     NBVAL is INTEGER array, dimension (NNB)
                     The values of the blocksize NB.

           NNS

                     NNS is INTEGER
                     The number of values of NRHS contained in the vector NSVAL.

           NSVAL

                     NSVAL is INTEGER array, dimension (NNS)
                     The values of the number of right hand sides NRHS.

           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.

           NMAX

                     NMAX is INTEGER
                     The leading dimension of the work arrays.
                     NMAX >= the maximum value of N in NVAL.

           A

                     A is COMPLEX*16 array, dimension (NMAX*NMAX)

           AINV

                     AINV is COMPLEX*16 array, dimension (NMAX*NMAX)

           B

                     B is COMPLEX*16 array, dimension (NMAX*NSMAX)
                     where NSMAX is the largest entry in NSVAL.

           X

                     X is COMPLEX*16 array, dimension (NMAX*NSMAX)

           XACT

                     XACT is COMPLEX*16 array, dimension (NMAX*NSMAX)

           WORK

                     WORK is COMPLEX*16 array, dimension
                                 (NMAX*max(3,NSMAX))

           RWORK

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

           NOUT

                     NOUT is INTEGER
                     The unit number for output.
