SetDiff1d

public final class SetDiff1d

Computes the difference between two lists of numbers or strings.

Given a list `x` and a list `y`, this operation returns a list `out` that represents all values that are in `x` but not in `y`. The returned list `out` is sorted in the same order that the numbers appear in `x` (duplicates are preserved). This operation also returns a list `idx` that represents the position of each `out` element in `x`. In other words:

`out[i] = x[idx[i]] for i in [0, 1, ..., len(out) - 1]`

For example, given this input:

x = [1, 2, 3, 4, 5, 6]
 y = [1, 3, 5]
 
This operation would return:
out ==> [2, 4, 6]
 idx ==> [1, 3, 5]
