Hi all,

I'm not sure if my previous email got through.
After struggling for days with FFT in GSL, I took the suggestion of the first reply I received and used FFTW.
I've deleted all my GSL code and solely rely on FFTW, works like a charm.
But thanks for all you suggestions, I appreciate it.

Does anyone have an explanation for this? I first thought that Python's and
C++ decimal rounding are different,, but would this have such a huge
different on the result?
You might want to check if the inverse transform reproduces the
original data in both cases.
