Atomic Subcharts

Encapsulate modal logic in reusable subcomponents

Reuse state components in multiple charts by using atomic subcharts. Generate reusable code from atomic subcharts. Reduce recompilation time for your model by recompiling only the atomic subcharts that you modify.

Reuse a State Multiple Times in a Chart

Use linked atomic subcharts to repeat the same configuration of states and transitions multiple times in a Stateflow® chart. Atomic subcharts are not supported in standalone Stateflow charts in MATLAB®. For more information, see Create Reusable Subcomponents by Using Atomic Subcharts.
