Linear algebra library for the Rust programming language.



lib.rs:

nalgebra

nalgebra is a linear algebra library written for Rust targeting:

  • General-purpose linear algebra (still lacks a lot of features…)
  • Real-time computer graphics.
  • Real-time computer physics.

Using nalgebra

You will need the last stable build of the rust compiler and the official package manager: cargo.

Simply add the following to your Cargo.toml file:

[dependencies]
// TODO: replace the * by the latest version.
nalgebra = "*"

Most useful functionalities of nalgebra are grouped in the root module nalgebra::.

However, the recommended way to use nalgebra is to import types and traits explicitly, and call free-functions using the na:: prefix:

#[macro_use]
extern crate approx; // For the macro assert_relative_eq!
extern crate nalgebra as na;
use na::{Vector3, Rotation3};

fn main() {
let axis  = Vector3::x_axis();
let angle = 1.57;
let b     = Rotation3::from_axis_angle(&axis, angle);

assert_relative_eq!(b.axis().unwrap(), axis);
assert_relative_eq!(b.angle(), angle);
}

Features

nalgebra is meant to be a general-purpose, low-dimensional, linear algebra library, with an optimized set of tools for computer graphics and physics. Those features include:
