Function nalgebra_glm::outer_product

pub fn outer_product<N: Number, R: Dimension, C: Dimension>(
    c: &TVec<N, R>, 
    r: &TVec<N, C>
) -> TMat<N, R, C> where
    DefaultAllocator: Alloc<N, 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.
