Stateflow simulink $toolbox/matlab/icons/simulinkicon.gif

Stateflow is an interactive design and simulation tool for event-driven systems. Stateflow provides the language elements required to describe complex logic in a natural, readable, and understandable form. It is tightly integrated with MATLAB and Simulink, providing an efficient environment for designing embedded systems that contain control, supervisory, and mode logic.

In addition, Stateflow can produce efficient production-quality code so that you can turn your thoughts and ideas into real systems.

Examples

Stateflow provides a complete environment in which you can model all types of reactive systems. It works closely with Simulink to provide a complete system simulation environment.
