Matrix Object in Javascript & Matrix Rotate Function

Question

Is there a native Javascript Matrix object? You know how theres a Date, Array, Object, is there a Matrix?

If not, which 3rd party library is best to use Matrices in Javascript?

Does anyone know of an open source Matrix function that rotates around a point? IE...

var myMatrix     = {tx: 1, ty: 0, ...other matrix values};
var rotMatrix    = rotate(myAngle, myMatrix);
var newRectPoint = {x: rotMatrix.tx, y: rotMatrix.ty};

There is no built-in matrix object in Javascript, but there are multi-dimensional arrays. There are libraries for matrices, but I don't use any, and thus can't name any. — Havvy

I think you can use underscore's zip.apply() for the purpose.

Though still no native math matrix object, there is a famous 3rd party library Math.js.

From its example, you can simply create matrix with:

var a = math.matrix([1, 4, 9, 16, 25]);
var b = math.matrix(math.ones([2, 3]));
