       DCHKTB

       Purpose:


            DCHKTB tests DTBTRS, -RFS, and -CON, and DLATBS.

       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.

           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.

           AB

                     AB is DOUBLE PRECISION array, dimension (NMAX*NMAX)

           AINV

                     AINV is DOUBLE PRECISION array, dimension (NMAX*NMAX)

           B

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

           X

                     X is DOUBLE PRECISION array, dimension (NMAX*NSMAX)

           XACT

                     XACT is DOUBLE PRECISION array, dimension (NMAX*NSMAX)

           WORK

                     WORK is DOUBLE PRECISION array, dimension
                                 (NMAX*max(3,NSMAX))

           RWORK

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

           IWORK

                     IWORK is INTEGER array, dimension (NMAX)

           NOUT

                     NOUT is INTEGER
                     The unit number for output.
