/*  -- LAPACK test routine (version 3.0) --   
       Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,   
       Courant Institute, Argonne National Lab, and Rice University   
       March 31, 1993   


    Purpose   
    =======   

    CCKLSE tests CGGLSE - a subroutine for solving linear equality   
    constrained least square problem (LSE).   

    Arguments   
    =========   

    NN      (input) INTEGER   
            The number of values of (M,P,N) contained in the vectors   
            (MVAL, PVAL, NVAL).   

    MVAL    (input) INTEGER array, dimension (NN)   
            The values of the matrix row(column) dimension M.   

    PVAL    (input) INTEGER array, dimension (NN)   
            The values of the matrix row(column) dimension P.   

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

    NMATS   (input) INTEGER   
            The number of matrix types to be tested for each combination   
            of matrix dimensions.  If NMATS >= NTYPES (the maximum   
            number of matrix types), then all the different types are   
            generated for testing.  If NMATS < NTYPES, another input line   
            is read to get the numbers of the matrix types to be used.   

    ISEED   (input/output) INTEGER array, dimension (4)   
            On entry, the seed of the random number generator.  The array   
            elements should be between 0 and 4095, otherwise they will be   
            reduced mod 4096, and ISEED(4) must be odd.   
            On exit, the next seed in the random number sequence after   
            all the test matrices have been generated.   

    THRESH  (input) 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.   

    NMAX    (input) INTEGER   
            The maximum value permitted for M or N, used in dimensioning   
            the work arrays.   

    A       (workspace) COMPLEX array, dimension (NMAX*NMAX)   

    AF      (workspace) COMPLEX array, dimension (NMAX*NMAX)   

    B       (workspace) COMPLEX array, dimension (NMAX*NMAX)   

    BF      (workspace) COMPLEX array, dimension (NMAX*NMAX)   

    X       (workspace) COMPLEX array, dimension (5*NMAX)   

    WORK    (workspace) COMPLEX array, dimension (NMAX*NMAX)   

    RWORK   (workspace) REAL array, dimension (NMAX)   

    NIN     (input) INTEGER   
            The unit number for input.   

    NOUT    (input) INTEGER   
            The unit number for output.   

    INFO    (output) INTEGER   
            = 0 :  successful exit   
            > 0 :  If CLATMS returns an error code, the absolute value   
                   of it is returned.   

    =====================================================================   


       Initialize constants and the random number seed.
