SCHKAA

Purpose:

SCHKAA is the main test program for the REAL LAPACK linear equation routines.

The program must be driven by a short data file. The first 15 records (not including the first comment line) specify problem dimensions and program options using list-directed input. The remaining lines specify the LAPACK test paths and the number of matrix types to use in testing. An annotated example of a data file can be obtained by deleting the first 3 characters from the following 40 lines:
