Function mat2::lmul_mut

pub fn lmul_mut<'out, T>(out: &'out mut [T; 4], m: &[T; 4]) -> &'out mut [T; 4] where
    T: Clone + Add<T, Output = T>,
    &'a T: Mul<&'b T, Output = T>, 

lmul_mut(A, B) does A = A * B

Example

let mut m = mat2::new_identity::<f32>();
mat2::lmul_mut(&mut m, &mat2::new_identity());
assert_eq!(m, mat2::new_identity::<f32>());
