Examples

Identity

let empty = mat4!();
assert_eq!(
    empty.as_ref(),
    &[
         [1.0, 0.0, 0.0, 0.0],
         [0.0, 1.0, 0.0, 0.0],
         [0.0, 0.0, 1.0, 0.0],
         [0.0, 0.0, 0.0, 1.0],
    ]
);

Full

let full = mat4!(
    0.1, 0.2, 0.3, 0.4,
    0.5, 0.6, 0.7, 0.8,
    0.9, 1.0, 1.1, 1.2,
    1.3, 1.4, 1.5, 1.6,
);
assert_eq!(
    full.as_ref(),
    &[
        [0.1, 0.2, 0.3, 0.4],
