Function bareiss::bareiss_determinant

pub fn bareiss_determinant<T>(
    matrix: &mut Vec<T>, 
    rows: usize
) -> Result<T, &'static str> where
    T: Sub<Output = T> + Div<Output = T> + Mul<Output = T> + Copy, 

Bareiss algorithm calculates the determinant of an integer square matrix only using integer arithmetics.

Examples

use bareiss::bareiss_determinant;

let mut matrix = vec![1, 2, 3, 10];
assert_eq!(bareiss_determinant(&mut matrix, 2).unwrap(), 4);
