Hey,
The “Clock” block in Simulink outputs the current simulation time at each simulation step. This block is useful for other blocks that need the simulation time. The output of the “Clock” block should be connected to the input of the MATLAB function block. As a result, the output of the MATLAB Function block will be “t^2”. For more information about the “Clock” block in Simulink, refer to the following link - https://www.mathworks.com/help/simulink/slref/clock.html.
The Simulink Data Inspector can be used to create plots and view the outputs of the simulation. Right click on the signals that need to be plotted and select “Log Selected Signals”. This enables signal logging with the Simulink Data Inspector. After the simulation is completed, clicking on the blue icon on top of the logged signals launches the Simulink Data Inspector. More information about creating plots using Simulink Data Inspector can be found here - https://www.mathworks.com/help/simulink/ug/create-plots-with-the-simulation-data-inspector.html.
To save the output as raw data, the “To File” block in Simulink can be used. The data can be saved to a “.mat” file as a Timeseries object or as a MATLAB Array, by setting the “SaveFormat” parameter. Refer to this link for more information about saving simulation data - https://www.mathworks.com/help/simulink/slref/tofile.html.
I have attached the Simulink model with the modifications listed above. Hope it helps!
