Dear all;

I'm gonig to use FFTW libraries in order to calculate the 3D-FFT of a
step function.
I defined the 3D step function on a 100*100*100 mesh.
then I installed fftw-3.1.2 package (fftw-3.1.2.tar.gz), but I don't
know how can I use it?
Please let me know if there is anyone that can help me.

I'm anxiously looking forward your reply and guidelines.

With my best regards,
Fatemeh

...how can I...
