Fourier Transforms

M

Mr Andrew Hall

Hi all,
Is there a way of performing fft's? I'm trying to convirt a heap of data from
the time domain to the frequency domain. Unfortunately I don't have access to
matlab at the moment.

I did find the fft command, but it seems to only work for data with 2^n entries.
This is pretty useless as I need to convirt to the frequency domain over a
specific time range.

Thanks for any help,
Andrew
