Split a vector into modulus batches

Split a vector into modulus batches

Usage

index_split(x, n)

Arguments

x

A vector.

n

An integer.

Value

A list with at most n elements. The i-th element is a vector containing all the elements of x belonging to the same equivalence class with respect to the modulus operation. That means \(x_1\) and \(x_2\) are both elements of out[i] if eqnx_1 mod n = x_2 mod n = i.
