how to know a Simulink model needs howmuch time to operate?how to know the speed of operation?

I have got 3 matlab simulink models which they do the same thing. And I want to study them in the case of speed of operating. I mean i am going to know which one of them is faster.

Hi @mehrdad mirzaei

To determine the speed of operation and the execution time of Simulink models, you can follow these steps:

1. Use the tic and toc Functions: You can use MATLAB's tic and toc functions to measure the time taken for the simulation to execute.

tic;
sim('your_model_name');
elapsedTime = toc;
fprintf('Elapsed time: %.2f seconds\n', elapsedTime);

2. Profiler:

• MATLAB provides a profiler tool that can be used to analyze the performance of your Simulink models.
• To use the profiler, go to the Simulink model, and in the menu, select Debug -> Performance Advisor.
• Alternatively, you can use the command:

profile on;
sim('your_model_name');
profile viewer;

3. Performance Advisor:

Simulink's Performance Advisor can help identify performance bottlenecks and suggest optimizations:

• Open your Simulink model.
• Go to Analysis -> Performance Advisor.
• Follow the steps to diagnose and improve the performance of your model.

By following these steps, you can effectively measure and compare the execution speed of your Simulink models to determine which one operates faster.
