gnatmake testmatrix.adb -

C files or library files?

With C files you do:

gcc -c c_file.c
gnatmake -c main_ada_file.adb
gnatbind main_ada_file.ali
gnatlink main_ada_file.ali c_file.o

With library files (import or object) it is simpler

gnatmake main_ada_file.adb --largs library_file.lib

(If you have only a shared library then it would require a bit more work.)

Better to create a gpr file for the binding and another one for the project
that uses them. With gpr files you can use GPS (GNAT IDE) as well as
command line:

gnatmake -Pproject_file.gpr

Simon meant to name function Internal rather imsl_f_eig_gen. It is a matter
of style. I agree it would be better.
