Looking for a sprite export that has matrix library, prefer to borrow than write my own.

If you are still looking for a matrix library, I tried starting one in Scratch.

Not ideal, but it does some basic operations. I took a stab at doing a matrix inverse as well. No determinant function or LU decomposition. A little wonky to use. I did not extensively test it either.
