# nalgebra
[![Build Status](https://travis-ci.org/sebcrozet/nalgebra.png?branch=master)](https://travis-ci.org/sebcrozet/nalgebra)
**nalgebra** is a linear algebra library written for Rust targeting:
* general-purpose linear algebra (still misses a lot of features…).
* real time computer graphics.
* real time computer physics.
An on-line version of this documentation is available [here](http://www.rust-ci.org/sebcrozet/nalgebra/doc/nalgebra/index.html).
## Using **nalgebra**
All the functionalities of **nalgebra** are grouped in one place: the `na` module.
This module re-exports everything and includes free functions for all traits methods doing
out-of-place modifications.
* You can import the whole prelude using:
```.ignore
use nalgebra::na::*;
```
The preferred way to use **nalgebra** is to import types and traits explicitly, and call
free-functions using the `na::` prefix:
```.rust
extern crate nalgebra;
use nalgebra::na::{Vec3, Rot3, Rotation};
use nalgebra::na;
fn main() {
let a = Vec3::new(1.0f64, 1.0, 1.0);
let mut b = Rot3::new(na::zero());
b.append_rotation(&a);
assert!(na::approx_eq(&na::rotation(&b), &a));
}
```
## Features
**nalgebra** is meant to be a general-purpose linear algebra library (but is very far from that…),
and keeps an optimized set of tools for computational graphics and physics. Those features include:
* Vectors with static sizes: `Vec0`, `Vec1`, `Vec2`, `Vec3`, `Vec4`, `Vec5`, `Vec6`.
* Square matrices with static sizes: `Mat1`, `Mat2`, `Mat3`, `Mat4`, `Mat5`, `Mat6 `.
* Rotation matrices: `Rot2`, `Rot3`, `Rot4`.
* Isometries: `Iso2`, `Iso3`, `Iso4`.
* Dynamically sized vector: `DVec`.
* Dynamically sized (square or rectangular) matrix: `DMat`.
* A few methods for data analysis: `Cov`, `Mean`.
* Almost one trait per functionality: useful for generic programming.
* Operator overloading using the double trait dispatch
[trick](http://smallcultfollowing.com/babysteps/blog/2012/10/04/refining-traits-slash-impls/).
For example, the following works:
```rust
extern crate nalgebra;
use nalgebra::na::{Vec3, Mat3};
use nalgebra::na;
fn main() {
let v: Vec3<f64> = na::zero();
let m: Mat3<f64> = na::one();
let _ = m * v; // matrix-vector multiplication.
let _ = v * m; // vector-matrix multiplication.
let _ = m * m; // matrix-matrix multiplication.
let _ = v * 2.0; // vector-scalar multiplication.
}
```
## Compilation
You will need the last rust compiler from the master branch.
If you encounter problems, make sure you have the last version before creating an issue.
```.ignore
git clone git://github.com/sebcrozet/nalgebra.git
cd nalgebra
make
```
You can build the documentation on the `doc` folder using:
```.ignore
make doc
```
