% The Kaiser-Bessel window is computed according to [3]_. The definition of the
% center (the zero) is in accordance with the definition of the centered dft. Other
% options are probably possible, the important aspect is that the function weighted
% by the Kaiser-Bessel window becomes fully periodizable. Note: generally a choice of
% beta = 8 is good, beta = 0 corresponds to a rectangle-function.
% By multiplying an array with the window prior to computing the FFT of it, periodicity
% effects of the discrete Fourier transform are suppressed. Accordingly, the Kaiser
% Bessel window improves the approximation of the continuous Fourier transform by
% the discrete one.
