Usage

Add this to your Cargo.toml:

[dependencies]
mathru = "0.1.2"

And then import the library using:

extern crate mathru;

Then import the modules and it is ready to be used:

extern crate mathru;
use mathru::algebra::linear::{Matrix};

// Compute the LU decomposition of a 2x2 matrix
let a: Matrix<f64> = Matrix::new(2, 2, vec![1.0, -2.0, 3.0, -7.0]);
let l_ref: Matrix<f64> = Matrix::new(2, 2, vec![1.0, 0.0, 1.0 / 3.0, 1.0]);

let (l, u, p): (Matrix<f64>, Matrix<f64>, Matrix<f64>) = a.dec_lu();

assert_eq!(l_ref, l);
