WebThe cross product is a classic. If you have zillion of such computation to do, try the following optimized version that requires half less multiplications: area = 0; for ( i = 0; i < N; i += 2 ) area += x [i+1]* (y [i+2]-y [i]) + y [i+1]* (x [i]-x [i+2]); area /= 2; I use array subscript for clarity.
