Function Documentation

   program schkaa
       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:
