Masking Example Models

The Simulink^® Masking example models help you to understand and configure mask parameters, properties, and features. See Simulink Masking Examples for more information on Masking models. 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.

Promote parameters to a mask	Parameter Promotion. Model: (slexMaskParameterPromotionExample)	Promote Block Parameters on a Mask
Execute Mask Callback	Mask Callback. Model: (slexMaskCallbacksExample)	Mask Callback Code
Display an Image as icon on a mask	Mask Display and Mask Initialization. Model: (slexMaskDisplayAndInitializationExample)	Add Image to Block Icon
Make a parameter invisible in the mask Disable a mask parameter	Dynamic Mask Callback. Model: (slexMaskDDGExample)
Set a mask to be self-modifying	Self Modifiable Library Block. Model: (slexMaskSelfModifiableExample)	Dynamic Masked Subsystem
Mask a variant subsystem	Masking Variant Blocks. Model: (slexMaskVariantExample)
Create a self-modifiable interface block	Self-Modifiable Interface Blocks. Model: (slexMaskSelfModifiableInterfaceBlocks)

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	slexMaskUnsafeCallbacksErrorExample
Setting parameters outside of the hierarchical boundary in nested masks may lead to unexpected behavior	slexMaskUnsafeNestedUsageErrorExample
