Complex Logic

模型复杂罗技c using Stateflow^®diagrams

To model complex logic in a Simulink^®模型，考虑使用状态流软件。

Stateflowextends Simulink with a design environment for developing state transition diagrams and flow charts. 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 products, providing an efficient environment for designing embedded systems that contain control, supervisory, and mode logic.
