The computation results differ in the least significant bit, which is normal and expected -- different computations lead to different round-off errors. In fact, I believe that my implementation is more accurate than the original, because it involves fewer computational steps, reducing round-off errors. Of course, my code finds exactly the same spikes and gaussians as the original program.
