Many engineering applications require control over when the block updates and produces output. Simulink®
provides a way to do this by allowing you to set the sample time for discrete and hybrid systems. You can further understand and visualize sample times in the model by using annotations, colors and the Sample Time Legend. Colors and annotations relate to different sample time groups existing in the model. The Legend helps you find different rate groups and navigate to them in the model.
