Phase Difference Measurement with Matlab

Phase difference measurement between two signals via DFT or cross-correlation.
The present code is a Matlab function that provides a measurement of the phase difference (as an angle) or time difference (as time duration) between two signals. In the first case, the measurement is based on the discrete Fourier transform, and in the second – on the cross-correlation computation. The methods are highly noise-resistive.
Several examples are given to clarify the usage of the function. For convenience, the input and output arguments are given at the beginning of the function.
The code is based on the theory described in:
