* Ensure that paired matrix operands are both matrices and of the same size * *

Parameters

mixed &$operand1 First matrix operand: * @param mixed &$operand2 Second matrix operand * @param integer $resize Flag indicating whether the matrices should be resized to match * and (if so), whether the smaller dimension should grow or the * larger should shrink. * 0 = no resize * 1 = shrink to fit * 2 = extend to fit
