.nf
          NM is INTEGER
          The number of values of M contained in the vector MVAL\&.

.nf
          MVAL is INTEGER array, dimension (NM)
          The values of the matrix row dimension M\&.

.nf
          PVAL is INTEGER array, dimension (NM)
          The values of the matrix row dimension P\&.

.nf
          QVAL is INTEGER array, dimension (NM)
          The values of the matrix column dimension Q\&.

\fINMATS\fP 
.PP
.nf
          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\&.

\fIISEED\fP 
.PP
.nf
          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\&.

.br
\fITHRESH\fP

.nf
          THRESH is REAL
          The threshold value for the test ratios\&.  A result is
