That won't be necessary -- the Fortran-implementation is guaranteed to win! Just to make sure, I timed it anyway (on somewhat larger arrays): Francesc's Solution: 0.062797403 Seconds/Trial Fortran Solution 1: 0.050316906 Seconds/Trial Fortran Solution 2: 0.052595496 Seconds/Trial Nathan's Solution: 0.055562282 Seconds/Trial Cython Solution: 0.06250751 Seconds/Trial Nathan's version runs over the data 6 times, and still does better than the Pyrex version. I don't know why! But, hey, this algorithm is parallelisable! Wait, no, it's bedtime.
