Re: Matlab vs. Octave speed of computation

[lorenzosan]

Thanks to all,
unfortunately I am not the only person who has written the code and I can
not post it here!
In the meanwhile I have avoided another loop with a series of floor and rem,
may be not optimized but I have seen a slight improvement in Matlab but a
good one in Octave. Now it is ''only'' twice slower.


I think I will try C++, at the end...

Thanks!
