The present code is a Matlab function that provides a Short-Time Cepstrum Computation of a given signal x[n]. The results are:
1) matrix with the one-sided amplitude cepstrum with time across columns and quefrency across rows;
2) quefrency vector;
3) time 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:
