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

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

Hello,

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

	Thank you,

carlo

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

recently, I have computed convolutions of real data in the context of a 
Hilbert transform

by gsl_fft_real_transform and it worked well.

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?

Greetings,

No, not to my knowledge.
