Run Individual Simulations

Run and control individual simulations directly from the Simulink® Editor or programmatically from the MATLAB® command prompt

Simulating a model gives you results of the algorithms that you build through the process of modeling. You can interact with the simulations by pacing the simulation, tuning model parameters, stopping or pausing the simulation, and displaying port values to evaluate the design of your model. Simulations help you understand the design and behavior of your model.

Simulate a model interactively by clicking the Run button in the Simulink Toolstrip, or programmatically using functions like sim and set_param in the MATLAB Command Window or a MATLAB script.

For information about running parallel and batch simulations, see Run Multiple Simulations.
