Description:
------------
in the file Matrix.php
in the function multiply(&$m1)
line 1106
if ($nc1 != $nr) {
should be
if ($nc != $nr1) {
The matrix multiplication doesn't work otherwise. Also I believe this is truly what the author intended because the error message in this if-block says:
'Incompatible sizes columns in matrix must be the same as rows in parameter matrix'
It's clear from the code that $nc belongs to the matrix and that $nr1 belongs to the parameter matrix.

This actually was fixed in the beta 0.8.5 (beta) version.
