Function converse_iter

Source 
pub fn converse_iter<K: ArrayKind>(
    order: FiniteFunction<K>,
) -> impl Iterator<Item = K::Index>
where
    K::Type<K::I>: NaturalArray<K>,
    K::I: Into<usize>,
Expand description

Given a FiniteFunction X → L, compute its converse, a relation r : L → X*, and return the result as an array of arrays, where r_i is the list of elements in X mapping to i.
