GSL Fourier Transform source?

Jun 24, 2013 at 7:16pm
Hello guys,

I'm looking for GSL's source of the function gsl_fft_real_transform() (the complex version is also OK). I want to write my own FFT which supports any length of data points, and GSL has done some efforts on that that I wanna have a look at to learn.

Any efforts are highly appreciated.

Cheers.

Thank you for the extremely detailed answer you provided. With all due respect, I'm not unable to go to GSL's website and search for the code; but the code is not available there, and I even downloaded the source package and I found nothing there but the call functions.

Any one knows where I can find the source code of that?

Thanks.

The source code is available on the page I linked. It took some digging and figuring out the macros but it looks like it is in
gsl-1.9/fft/real_main.c

Thanks man. I have problems dealing with macros, that's why I couldn't find it.
