Hiding model content

Hi,

What is the easiest way to hide the model content from third-party viewers? Is there a way to pre-compile the model in a specific format that cannot be reverse-engineered?

My scope is to share my Simulink model with others without revealing the content of the model itself. The users should only be able to use is as a black box, feeding it with data and getting the results.

Many thanks in advance for your help!

If you have RealTime workshop license then there are 2 ways of protecting you your model-

• You can genearte a s-function from the model, compile the s-function to mex file and deliver only mex-file. Mex file can be used with s-function block in model. See Generated S-Function>and <http://www.mathworks.com/support/solutions/en/data/1-1BUQG/index.html?solution=1-1BUQG
• You can generate a protected model (.mdlp) through model rerencing. See Protecting Referenced Models

Yes. Protected Model was something I missed. Side note, that this functionality is only a couple of releases old and will obvously not work for older releases.

Most customers create an S-Function from the part of the model that contains intellectual property by auto-generating the s-function with Simulink Coder (former Real-Time Worpshop).

Most large customers will have that product available in a concurrent license. If you are a smaller company, you may not find the value for protecting the IP enough.

Thank you both for the detailed answers! They certainly helped me a lot!
