Subject: [Caml-list] Create Array of floats from string
Date: Wed, 26 Apr 2017 10:48:30 +0000 [thread overview]
Message-ID: <2C817F94-9BF5-451F-BB12-706E441312D0@mail.uio.no> (raw)
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 *)
/Jon
