This MATLAB exercise compares and contrasts three algorithms for computing the complex cepstrum of two finite duration sequences. The three methods are the analytical method (with root finding using the MATLAB function roots), the conventional cepstral computation using the MATLAB signal processing toolbox function cceps, and the conventional FFT method of cepstral computation based on computing the inverse Fourier transform of the complex logarithm of the Fourier transform of the signal (with phase unwrapping).
