Using Simulink

Associating User Data with Blocks

You can use Simulink's set_param command to associate your own data with a block. For example, the following command associates the value of the variable mydata with the currently selected block.

• set_param(gcb, 'UserData', mydata)
  

The value of mydata can be any MATLAB data type, including arrays, structures, objects, and Simulink data objects. Use get_param to retrieve the user data associated with a block.

• get_param(gcb, 'UserData')
  

The following command causes Simulink to save the user data associated with a block in the model file of the model containing the block.

• set_param(gcb, 'UserDataPersistent', 'on');
