15* =============
16*>
17*> \verbatim
18*>
19*> SCHKAA is the main test program for the REAL LAPACK
20*> linear equation routines
21*>
22*> The program must be driven by a short data file. The first 15 records
23*> (not including the first comment line) specify problem dimensions
24*> and program options using list-directed input. The remaining lines
25*> specify the LAPACK test paths and the number of matrix types to use
26*> in testing. An annotated example of a data file can be obtained by
27*> deleting the first 3 characters from the following 40 lines:
28*> Data file for testing REAL LAPACK linear eqn. routines
29*> 7 Number of values of M
30*> 0 1 2 3 5 10 16 Values of M (row dimension)
31*> 7 Number of values of N
32*> 0 1 2 3 5 10 16 Values of N (column dimension)
33*> 1 Number of values of NRHS
34*> 2 Values of NRHS (number of right hand sides)
35*> 5 Number of values of NB
36*> 1 3 3 3 20 Values of NB (the blocksize)
37*> 1 0 5 9 1 Values of NX (crossover point)
38*> 3 Number of values of RANK
39*> 30 50 90 Values of rank (as a % of N)
40*> 20.0 Threshold value of test ratio
