If you want, you might consider steeling some code from (even better: adding some code to ;) Lacaml: http://lacaml.sourceforge.net/ It's intended as a low-level library that should support the Fortran-interfaces of BLAS/LAPACK with Bigarrays as close as possible + some extras, which are written in C. Currently only the functions that I need are implemented (mostly linear regression stuff), but adding further ones is very easy. You may also want to write a higher-level maths package that makes use of this low-level library. > The biggest problem is that there is no OCaml build in type complex > and that the Bigarray doesn't have complex too (sometime ago I read > that someone was thinking about adding complex numbers to the Bigarray > module, I would appreciate this very much). Xavier once told me that he is intending to add support for the complex domain to the Bigarray-module. I don't know whether this will be possible for the next release. It's not important to me, because I (currently) don't need complex numbers.
