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 by clicking theRunbutton on the Simulink Editor, or entering simulation commands, for example,simandset_paramin the MATLAB Command Window or a MATLAB file.

To learn about multiple simulations, seeRunning Multiple Simulations.
