Is there someone who can help me to calculate and plot the power spectrum
of a 2D field?
I have already calculated the power spectral density (it's a 3D function)
of the matrix through the FFt of the same matrix, you can use various
techniques, for example using the periodogram, but now i need the power
spectrum of the field so...? How can i do?
(PS: for example in turbulence you give a 3D field and you can compute the
power spectra, how? Therefore I am in the 2D input case)
Is there someone who have already done any Mathematica routine?
Thank you very much,
Matteo.
