2D FFT - KeithB - 03-23-2017 06:36 PM
Is there a way to do a 2D FFT on the Prime?

create two Vandermonde() of the size you want.
and use the double summation that defines 2D FFT

"Vandermonde"? Even google translate gives up.

vandermonde([1,e^(-2pi*i/3),e^(-4pi*i/3)]) to create 3x3 matrix
and use the definition for 2D FFT:
