Calculating Phase difference from workspace data

Hi,

As you can see from the diagram below, I have generated two wave functions from the workspace data and now I am interested in calculating/obtaining the phase difference between the two. Is there any efficient way of doing it in MATLAB or some mathematical formulation that I might be able to use?

FYI: My aim is to plot the bode plot eventually from different sets of data, let's say for an unknown system.
