I think you are too late: the draft for the relevant part of Ada2012 is at http://www.ada-auth.org/standards/12rm/html/RM-G-3.html. I believe that the gate closed in November '09. The issues on Ada2005 are at http://www.ada-auth.org/AI05-SUMMARY.HTML, none of them ask for extended matrix operations, so no wonder there's no change. I know this is a chicken-and-egg thing.

In my Linux BASH shell it seems to be straightforward: ../test_generic_complex_eigenvalues < test_generic_complex_eigenvalues.dat > output.txt I hope that's right. Now if I compare with the expected output, diff output.txt test_generic_complex_eigenvalues.out I find that all of the numbers in the 2 files are different. Anything to worry about? (I say no;-) J.

(I say no;-) > > J. I haven't had the time to test the dat file yet. Just one reminder which I quote from an earlier post: The program doesn't exit well however. When the program (test_generic_complex_eigenvalues.ada) it will display the results but in my GPS editor the line 102 is highlighted. This is where the program stops. If the program would run fine then I would have finally got this line displayed: DONE test_generic_complex_eigenvalues (at the bottom of test_generic_complex_eigenvalues.ada). Do you have the same problem? YC

I haven't had the time to test the dat file. One question from an earlier post: The program doesn't exit well however. When the program (test_generic_complex_eigenvalues.ada) it will display the results but in my GPS editor the line 102 is highlighted. This is where the program stops. If the program would run fine then I would have finally got this line displayed: DONE test_generic_complex_eigenvalues (at the bottom of test_generic_complex_eigenvalues.ada).
