.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\&.

          elements should be between 0 and 4095, otherwise they will be
          reduced mod 4096, and ISEED(4) must be odd\&.
