I'm using this program:
archives_voir.php?id=1894

But it only works for (EVEN) number of elements (See the attachment below).

Any help would be appreciated

As shown on first page, the algorithm used only works for dimensions being powers of 2 (not only even !).

Thanks, didn't see it...
Is there any program rather than this one?
I couldn't find anything

I don't think there is another one... I couldn't fint one either.
Make a good one and you'll probably help many people who need that !

(Well, in fact, any discrete Fourier transform algorithm could be used on calc (not only FFT) : the difference between a O(n^2) naive algorithm and a O(n*log(n)) one will hardly be seen for dimensions <= 1000... and larger dimensions are not very often used on calc !)

Thanks, I'll try and figure out something...
