scale method
Scale matrix m by s and replace this matrix
Implementation
Mat33 scale(Mat33 m, double s ) {
List<double> te = elements, tm = m.elements;
te[0] = tm[0] * s; te[1] = tm[1] * s; te[2] = tm[2] * s;
te[3] = tm[3] * s; te[4] = tm[4] * s; te[5] = tm[5] * s;
te[6] = tm[6] * s; te[7] = tm[7] * s; te[8] = tm[8] * s;
return this;
