## About

[Matrix.js](https://github.com/angusgibbs/matrix) is a JavaScript utility library
for working with [matrices](http://wikipedia.org/wiki/Matrix_(Mathematics\)). It
currently supports:

* Adding matrices
* Subtracting matrices
* Multiplying matrices
* Finding the determinant of a *n* by *n* matrix
* Creating a *n* by *n* identity matrix
* Raising a *n* by *n* matrix to the *x<sup>th</sup>* power
* Multiplying each element in the matrix by a scalar
* Checking two matrices for equivalence
* Inverting a matrix

For more information (including an installation guide), see the [docs](https://github.com/angusgibbs/matrix/blob/master/docs/getting_started.md).

## Contributing

Patches welcome, just make sure there are matching unit tests. Tests use
[mocha](http://visionmedia.github.com/mocha/) with [expect.js](https://github.com/LearnBoost/expect.js). To install, just `cd` into the directory and run `npm install`.
