How to encrypt the module

Hello, everyone, I want to ask a question. Now using Simulink to build a model, which has mine own write a few modules I want to package the modules to others to use. But do not want others to see the contents of the model So my question is： how to encrypt? By the way, I tried to generate the S function method, which can't meet my needs. So, there are other ways to do it?

Thanks a lot. Finally, I used S-function.
