In the Simulink® Editor, open the Property Inspector. Select View > Property Inspector.
With no selection at the top level of your model, in the Properties tab, in the Callbacks section, select the callback you want to set.
In the box, enter the functions you want the callback to perform.
The execution of callbacks for model referencing reflects the order in which the top model and the model it references execute their callbacks. For example, suppose:
Model A references model B.
Model A has a
that creates variables in the MATLAB workspace.
Model B has a
that clears the MATLAB workspace.
Simulating model A triggers rebuilding the referenced model B.
When Simulink rebuilds model B, it opens and closes model
B and invokes the model B
the MATLAB workspace, including the variables created by the
Instead of using a
CloseFcn callback for
model B, you can use a
StopFcn callback in model
A to clear the variables used by the model from the MATLAB workspace.
