In 2002 there was a short discussion on this list on a convolution
interface for GSL and Brian wrote it down in fft/TODO

Has anyone implemented that or parts of it by now?

No, not to my knowledge.

recently, I have computed convolutions of real data in the context of a
Hilbert transform
by gsl_fft_real_transform and it worked well.

There is no ready made routine, because the best choice of algorithm
is problem-dependent. (e.g. which type of fft to use)

Hello,
is there any, already made, way to perform the convolution between two
gsl_vectors in GSL ?
Thank you,
carlo

I've added it to the TODO list (fft/TODO) in case anyone wants to work
on it.

Hello
Â
Has someone made a (temporal) convolution for GSL? (and willing to share)
Is a convolution going to be added in GSL?
Â
Thank you for such a nice library.
