Extensions

We add extensions for Int and Float arrays to make them bin-able, comparable, sexpable, and blit-able (via Blit.S). Permissioned provides fine-grained access control for arrays.

module Int = Core.Array.Int
module Float = Core.Array.Float
module Permissioned = Core.Array.Permissioned

The Permissioned module gives the ability to restrict permissions on an array, so you can give a function read-only access to an array, create an immutable array, etc.

include module type of struct include Extended_array end

Extensions to Core.Core_array.

val random_split : ?random_state:Core.Random.State.t -> 'a array -> p:float -> 'a array * 'a array

makes a random split & subset of an array; p (the fraction that you want to split) is constrained to be 0, 1. Note that the length of the first array will be the closest integer to the fraction you desired, meaning that each element is NOT selected with probability exactly p.

val random_sub : ?random_state:Core.Random.State.t -> 'a array -> p:float -> 'a array
