       Courant Institute, Argonne National Lab, and Rice University   
       December 7, 1999   


    Purpose   
    =======   

    DCHKTR tests DTRTRI, -TRS, -RFS, and -CON, and DLATRS   

    Arguments   
    =========   

    DOTYPE  (input) 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      (input) INTEGER   
            The number of values of N contained in the vector NVAL.   

    NVAL    (input) INTEGER array, dimension (NN)   
            The values of the matrix column dimension N.   

    NNB     (input) INTEGER   
            The number of values of NB contained in the vector NBVAL.   

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

    NNS     (input) INTEGER   
            The number of values of NRHS contained in the vector NSVAL.   

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

    THRESH  (input) 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  (input) LOGICAL   
            Flag that indicates whether error exits are to be tested.   

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

    A       (workspace) DOUBLE PRECISION array, dimension (NMAX*NMAX)   

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

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

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

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

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

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

    IWORK   (workspace) INTEGER array, dimension (NMAX)   

    NOUT    (input) INTEGER   
            The unit number for output.
