41*> \param[in] TSTERR
42*> \verbatim
43*> TSTERR is LOGICAL
44*> Flag that indicates whether error exits are to be tested.
45*> \endverbatim
46*>
47*> \param[in] NM
48*> \verbatim
49*> NM is INTEGER
50*> The number of values of M contained in the vector MVAL.
51*> \endverbatim
52*>
53*> \param[in] MVAL
54*> \verbatim
55*> MVAL is INTEGER array, dimension (NM)
56*> The values of the matrix row dimension M.
57*> \endverbatim
58*>
59*> \param[in] NN
60*> \verbatim
61*> NN is INTEGER
62*> The number of values of N contained in the vector NVAL.
63*> \endverbatim
64*>
65*> \param[in] NVAL
66*> \verbatim
67*> NVAL is INTEGER array, dimension (NN)
68*> The values of the matrix column dimension N.
69*> \endverbatim

71*> \param[in] NNB
72*> \verbatim
73*> NNB is INTEGER
74*> The number of values of NB contained in the vector NBVAL.
75*> \endverbatim
76*>
77*> \param[in] NBVAL
78*> \verbatim
79*> NBVAL is INTEGER array, dimension (NNB)
80*> The values of the blocksize NB.
