MATLAB: How to find signals, which are defined in matlab-workspace, but not used in the SimulinkModel

MATLABsimulinkworkspace

My Problem is, that I have defined a lot of signals in my *.m files and while working on my model I stoped using them.
Now I have to do something like a "Clean up" and have to find the unused Signals what are in the WS but not used in the Model.
Does anyone have a fast solution for that?
Does there maby already exist some model check or report for that?
Best Regards
Lukas

Right click on your model, select "Find Reference Variables". Highlight all referenced variables, right click, select "Export Selected"
