[Help-gsl] Re: Help-gsl Digest, Vol 83, Issue 15

[Philip Ogunbona]

Marco,
The 2D Fourier transform is separable and you can apply Fourier
transform to 2D data by performing a 1D row-wise operation followed by a
1D column-wise operation. You need to carefully organise your data and
intermediate results.
I hope this helps.

Regards,
Philip
