Matrix3x2d.scale

Apply scaling to this matrix by uniformly scaling the two base axes by the given <code>xyz</code> factor. <p> If <code>M</code> is <code>this</code> matrix and <code>S</code> the scaling matrix, then the new matrix will be <code>M * S</code>. So when transforming a vector <code>v</code> with the new matrix by using <code>M * S * v</code>, the scaling will be applied first!

@see #scale(double, double)

@param xy the factor for the two components @return this
