The present code is a Matlab program for Time-Frequency analysis of a given (non-stationary) signal. The results are:
1) graphical representation of the signal in the time domain;
2) graphical representation of the signal in the frequency domain (via FFT);
3) graphical representation of the signal in the time-frequency domain (via STFT).

The code is based on the theory described in:
