graphics/matrices

[stinkyfax]

No doubt they are not making us a graphics engine to play with.
But since I have some experience in graphics, I'd love to give a try to simple 2d animation using matrices and matrix manipulation (rotation, translation, etc)
I haven't seen anything like arrays, vectors, matrices (array of arrays) in the x-fi wiki functions list, are there any?
I'd love to hear any experience you've got related to this topic.

P.S. I've read some lua documentation and found out that tables can store store tables which will lead to matrices.
What about Float processing? Is there any information on the processor being used and it's specifications?
