**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:

|
|
|
|
|

|
|
|
|
* Vectors with static sizes: `Vec0`, `Vec1`, `Vec2`, ..., `Vec6`.
|
|
|
|
|
|
* Square matrices with static sizes: `Mat1`, `Mat2`, ..., `Mat6 `.
|
|
|
|
|
|
* Dynamically sized vector: `DVec`.
|
|
|
|
|
|
* Dynamically sized (square or rectangular) matrix: `DMat`.
|
|
|
|
|
|
* Geometry-specific matrix wrapper to ensure at compile-time some properties: `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
|
2013-06-15 21:11:50 +08:00
|
|
|
|
You will need the last rust compiler from the master branch.
|
2013-07-25 05:54:54 +08:00
|
|
|
|
If you encounter problems, make sure you have the last version before creating an issue.

|
|
|
|
git clone git://github.com/sebcrozet/nalgebra.git
|
|
|
|
|
|
cd nalgebra
|
|
|
|
|
|
make

|
|
|
|
|
2013-09-28 06:12:18 +08:00
|
|
|
|
There is also a light, but existing, documentation for most functionalities. Use `make doc` to
|
|
|
|
|
|
generate it on the `doc` folder.

**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
