32*> ZCKGLM tests ZGGGLM - subroutine for solving generalized linear
33*> model problem.
34*> \endverbatim
35*
36* Arguments:
37* ==========
38*
39*> \param[in] NN
40*> \verbatim
41*> NN is INTEGER
42*> The number of values of N, M and P contained in the vectors
43*> NVAL, MVAL and PVAL.
44*> \endverbatim
45*>
46*> \param[in] NVAL
47*> \verbatim
48*> NVAL is INTEGER array, dimension (NN)
49*> The values of the matrix row dimension N.
50*> \endverbatim
51*>
52*> \param[in] MVAL
53*> \verbatim
54*> MVAL is INTEGER array, dimension (NN)
55*> The values of the matrix column dimension M.
56*> \endverbatim
57*>
58*> \param[in] PVAL
59*> \verbatim
60*> PVAL is INTEGER array, dimension (NN)
61*> The values of the matrix column dimension P.
62*> \endverbatim
63*>
64*> \param[in] NMATS
65*> \verbatim
66*> NMATS is INTEGER
67*> The number of matrix types to be tested for each combination
68*> of matrix dimensions. If NMATS >= NTYPES (the maximum
69*> number of matrix types), then all the different types are
70*> generated for testing. If NMATS < NTYPES, another input line
71*> is read to get the numbers of the matrix types to be used.
72*> \endverbatim
73*>
74*> \param[in,out] ISEED
75*> \verbatim
76*> ISEED is INTEGER array, dimension (4)
77*> On entry, the seed of the random number generator. The array
78*> elements should be between 0 and 4095, otherwise they will be
79*> reduced mod 4096, and ISEED(4) must be odd.
80*> On exit, the next seed in the random number sequence after
81*> all the test matrices have been generated.
82*> \endverbatim
83*>
84*> \param[in] THRESH
85*> \verbatim
86*> THRESH is DOUBLE PRECISION
87*> The threshold value for the test ratios. A result is
88*> included in the output file if RESID >= THRESH. To have
89*> every test ratio printed, use THRESH = 0.
90*> \endverbatim
91*>
92*> \param[in] NMAX
93*> \verbatim
94*> NMAX is INTEGER
95*> The maximum value permitted for M or N, used in dimensioning
96*> the work arrays.
97*> \endverbatim
98*>
99*> \param[out] A
100*> \verbatim
101*> A is COMPLEX*16 array, dimension (NMAX*NMAX)
102*> \endverbatim
103*>
104*> \param[out] AF
105*> \verbatim
106*> AF is COMPLEX*16 array, dimension (NMAX*NMAX)
107*> \endverbatim
108*>
109*> \param[out] B
110*> \verbatim
111*> B is COMPLEX*16 array, dimension (NMAX*NMAX)
112*> \endverbatim
113*>
114*> \param[out] BF
115*> \verbatim
116*> BF is COMPLEX*16 array, dimension (NMAX*NMAX)
117*> \endverbatim
118*>
119*> \param[out] X
120*> \verbatim
121*> X is COMPLEX*16 array, dimension (4*NMAX)
122*> \endverbatim
123*>
124*> \param[out] RWORK
125*> \verbatim
126*> RWORK is DOUBLE PRECISION array, dimension (NMAX)
127*> \endverbatim
128*>
129*> \param[out] WORK
130*> \verbatim
131*> WORK is COMPLEX*16 array, dimension (NMAX*NMAX)
132*> \endverbatim
133*>
134*> \param[in] NIN
135*> \verbatim
136*> NIN is INTEGER
137*> The unit number for input.
138*> \endverbatim
139*>
140*> \param[in] NOUT
141*> \verbatim
142*> NOUT is INTEGER
143*> The unit number for output.
144*> \endverbatim
145*>
146*> \param[out] INFO
147*> \verbatim
148*> INFO is INTEGER
149*> = 0 : successful exit
150*> > 0 : If ZLATMS returns an error code, the absolute value
151*> of it is returned.
152*> \endverbatim
