在 MATLAB 中执行

将独立的 Stateflow^® 图作为对象在 MATLAB^® 中执行

使用状态图设计逻辑，并将该逻辑作为 MATLAB 程序执行。在 Stateflow 编辑器中执行图并对其进行单元测试。用图来控制用户界面和数据处理应用程序的行为。

Model a Communications Protocol by Using Chart Objects

Use a standalone Stateflow® chart to model a frame-synchronization and symbol-detection component in a communications system. Standalone charts implement classic chart semantics with MATLAB® as the action language. You can program the chart by using the full functionality of MATLAB, including those functions that are restricted for code generation in Simulink®. For more information, see Create Stateflow Charts for Execution as MATLAB Objects.

Implement a Financial Strategy by Using Stateflow

Use a standalone Stateflow® chart to model a financial trading strategy known as Bollinger Bands. Standalone charts implement classic chart semantics with MATLAB® as the action language. You can program the chart by using the full functionality of MATLAB, including those functions that are restricted for code generation in Simulink®.
