CCKGLM

Purpose:
 CCKGLM tests CGGGLM - subroutine for solving generalized linear
                       model problem.
Parameters
[in]NN
          NN is INTEGER
          The number of values of N, M and P contained in the vectors
          NVAL, MVAL and PVAL.
[in]NVAL
          NVAL is INTEGER array, dimension (NN)
          The values of the matrix row dimension N.
[in]MVAL
          MVAL is INTEGER array, dimension (NN)
          The values of the matrix column dimension M.
[in]PVAL
          PVAL is INTEGER array, dimension (NN)
          The values of the matrix column dimension P.
[in]NMATS
          NMATS is 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.
[in,out]ISEED
          ISEED is 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.
[in]THRESH
          THRESH is REAL
          The threshold value for the test ratios.  A result is
          included in the output file if RESID >= THRESH.  To have
          every test ratio printed, use THRESH = 0.
[in]NMAX
          NMAX is INTEGER
          The maximum value permitted for M or N, used in dimensioning
          the work arrays.
[out]A
          A is COMPLEX array, dimension (NMAX*NMAX)
[out]AF
          AF is COMPLEX array, dimension (NMAX*NMAX)
[out]B
          B is COMPLEX array, dimension (NMAX*NMAX)
[out]BF
          BF is COMPLEX array, dimension (NMAX*NMAX)
[out]X
          X is COMPLEX array, dimension (4*NMAX)
[out]RWORK
          RWORK is REAL array, dimension (NMAX)
[out]WORK
          WORK is COMPLEX array, dimension (NMAX*NMAX)
[in]NIN
          NIN is INTEGER
          The unit number for input.
[in]NOUT
          NOUT is INTEGER
          The unit number for output.
[out]INFO
          INFO is INTEGER
          = 0 :  successful exit
          > 0 :  If CLATMS returns an error code, the absolute value
                 of it is returned.
