[Caml-list] What are people using for linear algebra?

[Erik de Castro Lopo]

Hi all,

What libraries are people using for linear algebra? I currently only
need simple things like multiplication and addition for now but
probably also need other stuff at some point.

I'd prefer something under the same license as the standard Ocaml
libraries.

TIA,
Erik

OCaml for Scientists describes the use of LACAML. See the eigenvalue example
here, for example:

Lacaml <http://www.ocaml.info/home/ocaml_sources.html#lacaml>.
There is unfortunately no debian package ATM.

Thanks Jon, I have it compiling.

You might hwoever want to fix the lacaml link on your page. The link
you have is broken but this one (from Christophe) works:

ocamlgsl, my bindings for the GSL library has some linear algebra too
: http://oandrieu.nerim.net/ocaml/gsl/
http://www.gnu.org/software/gsl/

mind that GSL's license is GPL, not LGPL.
