Hi,  
I know this is a stupid question but I need to do some FFT in my programs recently and I don’t seem to be able to find the right documentation about the instructions I can use, and working examples on the syntax. Can somebody please point me to the right documentation about that? I know Julia uses the FFTW library, but some docs on how to use it under Julia would be great 🙂

Thanks a lot,

Ferran

Ah, thanks, that was it. Couldn’t find it, sorry…
