Examples and How To

Model Callbacks

Specify MATLAB® code that executes at certain action points for models, for example after the model loads or when you save it.

Block Callbacks

Set block callbacks that execute when blocks are loaded, opened, or edited.

Port Callbacks

Set callbacks on input and output ports that execute every time the connectivity of these ports changes.

Callback Tracing

Use callback tracing to determine the callbacks that Simulink® invokes.
