Does anyone know where I might find a PHP matrix math library which is still actively maintained?

I need to be able to do the basic matrix operations like reduce, transpose (including non-square matrices), invert, determinant, etc.

This question was asked in the past, then closed with no answers. Now I need an answer to the same question. See these links to related questions:

Matrix artihmetic in PHP? http://stackoverflow.com/questions/435074/matrix-arithmetic-in-php-again

I was in the process of installing the pear Math_Matrix library when I saw these and realized it wouldn't help me. (Thanks Ben for putting that comment about transpose in your question.)

I can code this stuff myself, but I would make me happier to see that there is a library for this somewhere.
