/*! # 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 = na::zero(); let m: Mat3 = 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 ``` ## **nalgebra** in use Here are some projects using **nalgebra**.
