LinearJS

========

**Warning: LinearJS doesn't check an operation can be applied to two objects

and it will NOT fail gracefully if you don't provide objects that can be operated on.**

About

-----

LinearJS is a library I started writing to use with some WebGL

applications I made. It allows you to do operations (mentioned below) on vectors

and matrices, no matter what their dimensions are. It has a pretty clean API

that is inspired by Sylvester and it just gets the job done.

Supported operations

--------------------

For vectors:

 * addition

 * subtraction

 * scaling

 * dot product

 * cross product (for 3d vectors only)

 * normalization

For matrices:

 * addition

 * subtraction

 * transpose

 * multiplication

Keep in mind that those operations are supposed to work for whatever dimensions

you like.

How to use

----------

In order to use LinearJS, you have to include the

following files in your project, in the exact order:

 * array.js

 * vector.js

 * matrix.js

matrix.js depends on vector.js, which both depend on array.js... you get it.

Now, some examples. First go matrices.

    var a = new Matrix( [ [ 1 ], [ 2 ], [ 3 ] ]);

    a = a.multiply( Matrix.rotateX( Math.PI / 6 ) );

And vectors.

    var v = new Vector( [ 1, 2 ] );

    v = v.add( new Vector( [ 3, 4 ] );
