**nalgebra** is a _n_-dimensional linear algebra library written with the rust
programming language.
## 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:
It is mainly focused on features needed for real-time physics. It should be
usable for graphics too.
* Vectors with static size: `Vec0`, `Vec1`, `Vec2`, ..., `Vec6`.
* Square matrices with static size: `Mat1`, `Mat2`, ..., `Mat6 `.
* Dynamically sized vector: `DVec`.
* Dynamically sized matrix: `DMat`.
* Geometry-specific matrix wrapper: `Rotmat`, `Transform`.
* Most well-known geometric functions.
* A few methods for data analysis: `Cov` (covariance), `Mean` (mean).
* Operator overloading using the double trait dispatch [trick](http://smallcultfollowing.com/babysteps/blog/2012/10/04/refining-traits-slash-impls/).
This allows using operators for both matrix/matrix multiplication and matrix/vector
multiplication for example.
* Almost one trait per functionality. This is very useful for generic programming.
Since there is almost one trait per functionality, one might end up importing a lot of traits. To
lighten your `use` prelude, all trait are re-exported by the `nalgebra::vec` and `nalgebra::mat`
modules. Thus, to bring every functionalities of `nalgebra` in scope, you can do:
```rust
use nalgebra::vec::*;
use nalgebra::mat::*;
```
## Compilation
You will need the last rust compiler from the master branch.

cd nalgebra
make
There is also a light, but existing, documentation for most functionalities. Use `make doc` to
generate it on the `doc` folder.
## nalgebra in use
* [nphysics](https://github.com/sebcrozet/nphysics): a real-time physics engine.
* [ncollide](https://github.com/sebcrozet/ncollide): a collision detection library.
* [kiss3d](https://github.com/sebcrozet/kiss3d): a minimalistic graphics engine.
Feel free to add your project to this list if you happen to use **nalgebra**!
## Design note
**nalgebra** is mostly written with non-idiomatic rust code. This is mostly because of limitations
of the trait system not allowing (easy) multiple overloading. Those overloading problems ares
worked around by this
