Create Block Callbacks

You can create block callbacks interactively or programmatically.

To create block callbacks interactively:

1. Right-click a block, and in the context menu, select Properties.
2. In the Block Properties dialog box, select the Callback tab.
3. Create the callback code.

To create a block callback programmatically, use the set_param command to assign MATLAB^® code to the block callback parameter.

ex: 

openFcn: -> m file to run
