Input a structure variable to a Matlab Function block

How can I input a structure variable (struct data type) to a Matlab Function block? The document states that I specify the parameter as input in the Matlab Function block and use a Bus Creator to feed the Matlab Function. How can I feed the variable to the Bus Creator? What should I use for the <object name> in the Ports and Data Manager?

Following the following steps to use a structure variable in the base workspace in a Matlab Function:

1. Double click the Matlab Function block to open it in the Editor. Click the Edit Data icon, third from the right at the tool bar, to open the Port and Data Manager
2. In the Port and Data Manager, add a data with the name of the variable in the base workspace
3. Set the Scope for the data as Parameter. UNCHECK Tunable (very important)
4. Set the Size: -1, Complexity: Inherited, Type: Inherited: Same as Simulink
5. click Apply

The structure variable will show up as a function input argument.
