Discrete fourier transformation from a list of x-y points

Question

What I\'m trying to do is, from a list of x-y points that has a periodic pattern, calculate the period. With my limited mathematics knowledge I know that Fourier Transformat

Answer 1

This page from Scipy shows you basic knowledge of how Discrete Fourier Transform works: http://docs.scipy.org/doc/numpy-1.10.0/reference/routines.fft.html

They also provide API for using DFT. For your case, you should look at how to use fft2.
