A trait for abstract matrix norms.

This may be moved to the alga crate in the future.

Required methods

fn norm<R, C, S>(&self, m: &Matrix<N, R, C, S>) -> N::SimdRealField where
    R: Dim,
    C: Dim,
    S: Storage<N, R, C>, 

Apply this norm to the given matrix.

fn metric_distance<R1, C1, S1, R2, C2, S2>(
    &self,
    m1: &Matrix<N, R1, C1, S1>,
    m2: &Matrix<N, R2, C2, S2>
) -> N::SimdRealField where
    R1: Dim,
    C1: Dim,
    S1: Storage<N, R1, C1>,
    R2: Dim,
    C2: Dim,
    S2: Storage<N, R2, C2>,
    ShapeConstraint: SameNumberOfRows<R1, R2> + SameNumberOfColumns<C1, C2>, 

Use the metric induced by this norm to compute the metric distance between the two given matrices.
