Execution inMATLAB

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.

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.
