Using Simulink

Linking Mask Parameters to Block Parameters

The variables associated with mask parameters allow you to link mask parameters with block parameters. This in turn allows a user to use the mask to set the values of parameters of blocks inside the masked subsystem.

To link the parameters, open the block's parameter dialog box and enter an expression in the block parameter's value field that uses the mask parameter. The mx + b masked subsystem, described earlier in this chapter, uses this approach to link the Slope and Intercept mask parameters to corresponding parameters of a Gain and Constant block, respectively, that reside in the subsystem.

You can use a masked block's initialization code to link mask parameters indirectly to block parameters. In this approach, the initialization code creates variables in the mask workspace whose values are functions of the mask parameters and that appear in expressions that set the values of parameters of blocks concealed by the mask.
