To the best of my knowledge, there is no built-in function called scanunpack in MATLAB or Simulink. It seems like the function you mentioned might be specific to your project or a custom function that you or someone else has created.
Without more information about the purpose or behavior of the scanunpack function, it is difficult to provide specific instructions on how to use it. I would recommend checking your project's documentation or reaching out to the creator of the function for more information.
If you can provide additional details or code snippets related to the scanunpack function, I would be happy to help you further.
