No the issue is not yet resolved. I am unable to find optimal gain values.

Can you count the number of output(s) available in your Simulink model? Perhaps you requested these three outputs (in individual vectored data form) from the Simulink model in the cost_func() function, but it's possible that you consolidated all the data into a single simulation output object named 'out', as pointed out by @Walter Roberson.
If you are unfamiliar with the object-oriented programming (the dot notation stuff), then better configure the Simulink model to log the requested data as tout, xout, yout, rmse (incorrect!), ise, iae, and itae.

You expect three outputs to be returned from sim() whereas only one output can be returned from sim() command

Sorry my goal was to clear all the errors as stated in your original question. Regarding the correctness of your question , it"s better you post a new question.

I suspect that your model has been configured to return a single output;
