Example

use faer::{mat, perm::swap_rows};

let mut m = mat![
    [1.0, 2.0, 3.0],
    [4.0, 5.0, 6.0],
    [7.0, 8.0, 9.0],
    [10.0, 14.0, 12.0],
];

let (a, b) = m.as_mut().two_rows_mut(0, 2);
swap_rows(a, b);

let swapped = mat![
    [7.0, 8.0, 9.0],
    [4.0, 5.0, 6.0],
    [1.0, 2.0, 3.0],
    [10.0, 14.0, 12.0],
];

assert_eq!(m, swapped);
