3 * -- LAPACK test routine (version 3.1.1) --
4 * Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..
5 * January 2007

7 * Purpose
8 * =======
9 *
10 * SCHKAA is the main test program for the REAL LAPACK
11 * linear equation routines
12 *
13 * The program must be driven by a short data file. The first 14 records
14 * specify problem dimensions and program options using list-directed
15 * input. The remaining lines specify the LAPACK test paths and the
16 * number of matrix types to use in testing. An annotated example of a
17 * data file can be obtained by deleting the first 3 characters from the
18 * following 36 lines:
19 * Data file for testing REAL LAPACK linear eqn. routines
20 * 7 Number of values of M
21 * 0 1 2 3 5 10 16 Values of M (row dimension)
22 * 7 Number of values of N
23 * 0 1 2 3 5 10 16 Values of N (column dimension)
24 * 1 Number of values of NRHS
25 * 2 Values of NRHS (number of right hand sides)
26 * 5 Number of values of NB
27 * 1 3 3 3 20 Values of NB (the blocksize)
28 * 1 0 5 9 1 Values of NX (crossover point)
29 * 3 Number of values of RANK
30 * 30 50 90 Values of rank (as a % of N)
31 * 20.0 Threshold value of test ratio
32 * T Put T to test the LAPACK routines
33 * T Put T to test the driver routines
34 * T Put T to test the error exits

7 * Purpose
8 * =======
9 *
10 * SCHKAA is the main test program for the REAL LAPACK
11 * linear equation routines
12 *
13 * The program must be driven by a short data file. The first 14 records
14 * specify problem dimensions and program options using list-directed
15 * input. The remaining lines specify the LAPACK test paths and the
16 * number of matrix types to use in testing. An annotated example of a
17 * data file can be obtained by deleting the first 3 characters from the
18 * following 36 lines:
19 * Data file for testing REAL LAPACK linear eqn. routines
20 * 7 Number of values of M
21 * 0 1 2 3 5 10 16 Values of M (row dimension)
22 * 7 Number of values of N
23 * 0 1 2 3 5 10 16 Values of N (column dimension)
24 * 1 Number of values of NRHS
25 * 2 Values of NRHS (number of right hand sides)
26 * 5 Number of values of NB
27 * 1 3 3 3 20 Values of NB (the blocksize)
28 * 1 0 5 9 1 Values of NX (crossover point)
29 * 3 Number of values of RANK
30 * 30 50 90 Values of rank (as a % of N)
31 * 20.0 Threshold value of test ratio
32 * T Put T to test the LAPACK routines
33 * T Put T to test the driver routines
34 * T Put T to test the error exits
