OEGeom3DMatrixMultiply

template<class T, class U>
void OEGeom3DMatrixMultiply(T *accumulator, const U *add)
template<class T, class U, class V>
void OEGeom3DMatrixMultiply(T *Product, const U *init, const V *add)

Performs \(3x3\) matrix multiplication. The first form computes \(accumulator *= add\), and the second form computes \(Product = init * add\). All of the inputs are nine element \(3x3\) matrices.
