This looks very nice david! Is it possible to use the vectorised, array support
within ocaml? i.e I'm a little leary of using NML for mid-large applications due
to the lack of type checking, but it does seem to be an excellent language for
scientific interrogation.
Have you looked at the GNU scientific library?
http://sourceware.cygnus.com/gsl
This is a wonderfully eclectic scientific library in C, with strong
control over float properties. An ocaml or MNL binding would be a
killer app.
