The keywordmutableis a storage class specifier in the C++ language grammar, although it doesn't affect storage duration or linkage. Storage class specifiers, except forthread_local, are not allowed on explicit specializations and explicit instantiations: ...

The generated code statically initializes parameter data with an assignment statement at the top of a .c or .cpp source file, outside of any function. The generated code dynamically initializes signal and state data as part of the initialization function of the model (named model_initialize by...
