I don't know if OWL rolls its own thing, but there is a "numeric nd-array" type in the standard library in ocaml [1]. In any case "native arrays" in ocaml or other are dynamic vectors, so it wouldn't make any sense to build numeric arrays on top of that. And in ocaml you're probably using inductive lists or trees more than dynamic vectors.. So it's not really "unsatisfying": different datastructures for different needs.
