Webb15 feb. 2010 · In fact the slow decay is the rule rather than the exception in such systems. The reason is that the relative measure of quantities with exponentially decaying correlations is zero. (To see this think about the limitations on the coefficients in Eq. (9), that would ensure decay bound from above by an exponential. Webb2 okt. 2024 · Therefore the FFT allows the Fourier coefficients to be directly computed. Here is the MWE of my solution to this problem, expanding the example given above: import numpy as np import matplotlib.pyplot as plt # Set the number of equal-time bins to create. n_bins = 101 # Set the number of Fourier coefficients to use. n_coeff = 51 # …
