get circuit (simulink electrical) output in matlab code

Hello. I have drawn a simple circuit (RLC with sinusoidal input) using electrical simulink.

I have two questions. How can I read circuit output for example resistor voltage and plot it in matlab code? (I know that we can use Sim command to call simulink models in a matlab code). And how can I modify the circuit (simulink model) in the code, for example change the voltage source frequency or add a new element at specific nodes? Many thanks for your time.

See the attached file (saved in R2020a) to see an example of reading the voltage and plotting it in MATLAB. Run the following code to plot the value

sim('sim_model');
plot(out.r_voltage)
