The present code is a Matlab function that provides a computation of the:
1) one-sided amplitude 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:
