If NMATS >= NTYPES (the maximum 00045 * number of matrix types), then all the different types are 00046 * generated for testing. If NMATS < NTYPES, another input line 00047 * is read to get the numbers of the matrix types to be used. 00048 * 00049 * ISEED (input/output) INTEGER array, dimension (4) 00050 * On entry, the seed of the random number generator. The array 00051 * elements should be between 0 and 4095, otherwise they will be 00052 * reduced mod 4096, and ISEED(4) must be odd. 00053 * On exit, the next seed in the random number sequence after 00054 * all the test matrices have been generated. 00055 * 00056 * THRESH (input) REAL 00057 * The threshold value for the test ratios. A result is 00058 * included in the output file if RESULT >= THRESH.
