Masking Example Models

The Simulink^® Masking example models help you to understand and configure mask parameters, properties, and features. The examples are grouped by type. In an example model:

• To view the mask definition, double-click the View Mask block.

• To view the mask dialog box, double-click the block.

There are certain bad practices, which when followed may result in unexpected behavior of the masking features. The following table shows some of the bad practices.

Bad Practice	Example Models
Use of Mask callbacks, where the callback modifies entities outside of its scope may result in unexpected behavior	Unsafe Mask Callback Error
Setting parameters outside of the hierarchical boundary in nested masks may lead to unexpected behavior	Nested Mask Error
