When you want to simulate the model using the current values for all model configuration parameter values, block parameter values, variable values, and so on, use the most basic syntax. out = sim("ModelName"); This syntax returns a single Simulink.
Modeling is a way to create a virtual representation of a real-world system that includes software and hardware.
Simulation is used to evaluate a new design, diagnose problems with an existing design, and test a system under conditions that are hard to reproduce in an actual 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.
