Suppose I have Array:
let arr1 = Array.create 9 (fun i -> i*i)
I am interested "reshape" array arr1 into array 3x3 . Possible?
Or if I have
let arr2 = Array2.create 3 3 0
fill arr2 with values of arr1
I prefer "reshape" for reduce usage memory space
let arr1 = Array.create 25000000 (fun i -> i*i)
let arr2 = Array2.create 5000 5000 0
