I think you have GNAT? Assuming that, you'll find their implementation
of Ada.Numerics.Generic_Real_Arrays in their Ada standard library;
you'll find this under the installation directory. On my Mac it's
/opt/gnat-gpl-2010-x86_64/lib/gcc/x86_64-apple-darwin9.6.0/4.3.6/adainclude/a-ngrear.ad[sb]
but on a Windows machine it'll be something li
<install-dir>\<gnat-release>\lib\gcc\<architecture>\<gcc-release>\adainclude\a-ngrear.ad[sb]
This will lead you to System.Generic_Real_BLAS (s-gerebl.ad[sb]) and
System.Generic_Real_LAPACK (s-gerela.ad[sb]), which are interfaces to
the corresponding external libraries.
Not sure that these will fit your 'simple' criterion, though!
