/*     .. Scalar Arguments .. */
/*     .. */
/*     .. Array Arguments .. */
/*     .. */

/*  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. */
