[Caml-list] Create Array of floats from string

[Jon Kleiser <jon.kleiser@ceres.no>]

Hi,

I am quite new to OCaml, and I am looking for the most efficient way to make an Array of floats from string. My solution this far looks like this, where dims is a global variable specifying the size of the Arrays (typically 300):

let make_vector vec_strings =
  let vec = Array.make !dims 0.0 in
  List.iteri (fun i str -> vec.(i) <- float_of_string str) vec_strings

let process_line line =
  let parts = Str.split (Str.regexp " ") line in
  make_vector (List.tl parts)	(* skipping first element which is not a float *)
