I'm currently working on a numerical (and some symbolics) computational environment in OCaml (but not interactive, it must work with a database, something like a distributed multidimensional spreadsheet). Looking at PsiLab, I had choosen the following approach: 1) bigarrays for matrices and large datasets, for multidimensional data - arrays or tuples of bigarrays (sic!). 2) conventional arrays for vectors 3) "compilation" of the functions (e.g. minimization function using $\chi^2$ for the given dataset and model) by producing a partially applied functions - it seems to be very effective with ocaml. But my problems are somewhat specific: relatively simple mathematical models with a large datasets (particle physics phenomenology). ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
