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.
