Hi everyone! I'm trying to obtain values of a scope plot to obtain two columns of X and the corrispondent Y value to plot a graph on Excel. Does anyone know how to do it?
Thank you in advance! I need it for my thesis

Click the second buttons on the "Scope" block to access the scope parameters. Click the "Data history" tab, check "Save data to workspace". Assume you use the default name "ScopeData", choose "Structure with time" for the format.
Once your simulation is done, go to MATLAB Command Window,
ScopeData.time will be the time vector and ScopeData.signals.values will be the signal values.
