Using Simulink

Setting Masked Block Dialog Parameters

Simulink defines a set of masked block parameters that define the current state of the masked block's dialog. You can use the mask editor to inspect and set many of these parameters. The Simulink get_param and set_param commands also let you inspect and set mask dialog parameters. The advantage? The set_param command allows you to set parameters and hence change a dialog's appearance while the dialog is open. This in turn allows you to create dynamic masked dialogs.

For example, you can use the set_param command at the MATLAB command line to specify callback functions to be invoked when a user changes the values of user-defined parameters. The callback functions in turn can use set_param commands to change the values of the masked dialog's predefined parameters and hence its state, for example, to hide, show, enable, or disable a user-defined parameter control.
