Cepstral Analysis with Matlab

Cepstral analysis including calculation of the cepstral coefficients and the vector of quefrencies.

The present code is a Matlab function that provides a computation of the:
1) one-sided real cepstrum;
2) quefrency vector.

An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.

The code is based on the theory described in:
