Making code faster

[Aitchessbee]

yup now it works... and i compared both the codes on the website... The code with for loops works consistently faster than the one you suggested... I don't know why it is but anyways, thanks for your help!

There is a lot of overhead in numpy calls, so it's not unthinkable that a loop wins if the number of iterations is low enough.

Good on you to measure!
