Execution in MATLAB

Execute standalone Stateflow^® charts as objects in MATLAB^®

Design logic by using state charts and execute that logic as MATLAB programs. Execute and unit test your chart in the Stateflow editor. Control the behavior of user interfaces and data processing applications through your chart.

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®.
