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 Editor 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®. For more information, see Create Stateflow Charts for Execution as MATLAB Objects.

Automate Control of Intelligent Vehicles by Using Stateflow Charts

Model a highway scenario with intelligent vehicles that are controlled by the same decision logic. Each vehicle determines when to speed up, slow down, or change lanes based on the logic defined by a standalone Stateflow® chart. Because the driving conditions (including the relative position and speed of nearby vehicles) differ from vehicle to vehicle, separate chart objects in MATLAB® control the individual vehicles on the highway.
