handle = load_system( sys ) loads the model sys into memory without opening the model in the Simulink® Editor.
After you load a model into memory, you can work with it using Simulink API commands.
Save changes to the model using save_system .
Simulink provides a graphical editor, customizable block libraries, and solvers for modeling and simulating dynamic systems.
It is integrated with MATLAB®, enabling you to incorporate MATLAB algorithms into models and export simulation results to MATLAB for further analysis.
