Write valid C/C++ code. When you include a custom header file, use the #include directive. You can also include extern declarations of variables or functions.
Additionally, for versions R2024a or later, you can include a custom header file without the #include directive. However, mixed declarations in a single configuration parameter set are not supported. For this parameter, mixed declarations occur when any one of the following conditions is met.
- Declaring header files with and without the #include directive.
- Include valid C/C++ code and declare header files without the #include directive.
