The present code is a Matlab function that provides a Short-Time Fourier Transform (STFT) of a given signal x[n]. The function is an alternative of the Matlab command “spectrogram”. The output of the function is:
1) a matrix with the complex STFT coefficients with time across the columns and frequency across the rows;
2) a frequency vector;
3) a 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:
