(1) A protected model can only be simulated on the same OS that it was created in. You would need to create a version of the protected model for every OS.
(2) Please refer to the doc below to understand what protected model contains.
A protected model file (.slxp) contains derived files that support the options that you select when you create the protected model.
Some of the supported functionality are OS-dependent. For example, to run a protected model in accelerator mode, it requires to generate C code and link it to C-MEX S-Function, which is an OS-specific process.
(3) As you may have seen in the document, the protected model does not contain C code inside, but derived files for your option that will be used for building process.
