lin_algebra

A Rust library for linear algebra.

Features

All operations are currently implemented for matrices over GF(2):

• Compute the echelon form of a matrix along with the history of all the row operations applied
• Compute the rank of the linear application represented by a matrix
• Compute the kernel of the linear application represented by a matrix
• Compute the image of the linear application represented by a matrix.

Installation

Add the dependency to your Cargo.toml:

[dependencies]
lin_algebra = "0.2.0"

Usage

use lin_algebra::gf2_matrix::GF2Matrix;
use lin_algebra::matrix::MatrixTrait;

fn main() {
    // Reduces echelon form

    let gf2_mat = gf2_matrix::GF2Matrix::new(
        vec![vec![1,0,0,0], vec![0,1,0,1], vec![0,1,0,1]]
    )
    let (educed_echelon_form, row_operations) = gf2_mat.echelon_form();

    println!("Reduces echelon form {:?}", educed_echelon_form);
    println!(
        "Row operation applied to reach the reduces echelon form {:?}", row_operations
    );

    // Kernel
    println!("Kenel {:?}", gf2_mat.kernel());

    // Image
    println!("Image {:?}", gf2_mat.image());

    // Rank
    println!("Rank {}", gf2_mat.rank());
}
