This package provides functions to compute the Fast Fourier Transform (FFT).
For an example see Examples.RealFFT1 where the following signal is computed during simulation
y = 5 + 3*sin(2*pi*2) + 1.5*cos(2*pi*3)
the continuous-time signal y is sampled and the FFT is computed with a call to realFFT(f_max=4, f_resolution=0.2), resulting in:
