Function vec4::scale_mat2

pub fn scale_mat2<'out, T>(
    out: &'out mut [T; 4], 
    m: &[T; 4]
) -> &'out mut [T; 4] where
    T: Real,
    &'a T: Mul<&'b T, Output = T>, 

Example

let mut v = vec4::new_one();
vec4::scale_mat2(&mut v, &[1_f32, 0_f32, 0_f32, 1_f32]);
assert_eq!(v, vec4::new_one());
