Use System Objects

Simulate systems using predefined System objects in system toolboxes

System objects enable you to model dynamic systems and process streamed data. These objects are available if you have one or more system toolboxes, such as DSP System Toolbox™, Communications Toolbox™, or Computer Vision Toolbox™. For an introduction to System objects, see What Are System Objects?

What Are System Objects?

A System object™ is a specialized MATLAB® object. System objects are designed specifically for implementing and simulating dynamic systems with inputs that change over time.
