Hello All,
I have a plot containing a simulated as well as an experimental data of a system in simulink . I want to calculate the Root mean square error (RMSE) of the data. Can anyone explain to me how to extract data from the scope and calculate the RMSE ?

To log the data from Scope block, check Save Simulation Data Using a Scope Block in Common Scope Block Tasks. To calculate RMSE (Root Mean Square Error),
RMSE = sqrt(mean((simulatedData - experimentalData).^2));

what about if one wants to find maximum error?
