Function nalgebra_glm::outer_product

pub fn outer_product<T: Number, const R: usize, const C: usize>(
    c: &TVec<T, R>,
    r: &TVec<T, C>
) -> TMat<T, R, C>

Treats the first parameter c as a column vector and the second parameter r as a row vector and does a linear algebraic matrix multiply c * r.
