Dear all,
I've been looking for this around, but couldn't yet find anything.
I would like to made a (discrete) Fourier transform by directly typing in the code. The target is not performance, but eventually modifying the source (integrated) function from [f(x)exp(-j2piux/N)] to something different.
Has anybody written such a code in IDL that can be modified? Or can anybody give me a working link to such a code?

Many thanks and sorry for wasting your time.
Cheers, Helder
