Array2D to Array

Question

I have Array2D of 0 and 1:

let rnd = System.Random()
let a = Array2D.init n n (fun i j  -> int(System.Math.Round(rnd.NextDouble() / index)) )

Answer 1

The function transforming from Array2D to Array is very handy in many situations.

You can keep it in Array2D module for convenient use.

module Array2D =
    let toArray (arr: 'T [,]) = arr |> Seq.cast<'T> |> Seq.toArray
