Mask Terminology
The rest of this chapter assumes that you know the following
definitions:
Mask Icon — An icon
that replaces a masked block's standard icon when the masked block
appears in a model. You can accept a default icon or provide drawing
code that defines the icon.
Mask Parameters — Optional
parameters that link to block parameters that exist under the mask.
Setting a mask parameter sets the associated block parameter.
Mask Initialization Code —
Optional MATLAB code that runs when needed to initialize the
masked subsystem. You can use initialization code to modify a masked
subsystem to reflect current parameter values.
Mask Callback Code —
Optional MATLAB code that runs whenever a mask parameter value
changes. You can use callback code to modify a mask dialog box to
reflect current parameter values.
Mask Documentation —
Optional information that names and briefly describes the masked block,
and provides Help information about how to use it.
Mask Dialog Box — A
dialog box that replaces the masked block's standard parameters dialog
box. The mask dialog box displays a block description, contains controls
that enable a user to set mask parameter values, and provides Help
information.
Mask Workspace — If
the mask uses mask parameters or initialization code, it has a mask
workspace that holds parameter and temporary values used by the mask.
