Hi Samuel,
thank you for your answer.
I tried to implement your idea but I dont get the results I want.
For a start I tried to do a 3D plot with only one FFT computation.
So my data looks like:
f= 1x256 - the frequency axis
y=1x256 - the amplitude
z=1x256 - the investigated case (the field consists of only ones)
plot3d3(f,y,z)
<http://mailinglists.scilab.org/file/n4035350/fft.png>
Hard to help without knowing how/what you set in f, y and z.
Here is a working example with inputs having the format of your (f,y,z):
x = 1:100;
plot3d3(x,x,x)
e = gce();
e.thickness = 3;
Samuel
