Below is a list of some of the C++ Interface limitations. In some cases a workaround is provided.
Creating objects of classes in the std namespace
- Workaround: example with std::stack
- std::wstring and other std::string variants
- Support starting in: R2020b
- std::complex
- Support starting in: R2022a
- std::vector as a class data member
- Support starting in: R2022a
Class templates with incomplete or no instantiations
- Workaround: example with Pair template
Arrays and vectors of class objects
- Support starting in: R2020a
void*
- Support starting in: R2021a
Function pointer
- Support starting in: R2021a
Preprocessor directives
- Workaround: preprocessor directives
Array of std::string
- Workaround: string arrays
- void foo(std::string[] s)
- std::vector<std::string>
- Support starting in: R2021a
Data member
- Array/Pointer data members
- Support starting in: R2020a
- Reference data members
More detail is supplied in the Workaround links, but these general steps apply:
To run the workaround examples on Windows®:
- Download or copy the C++ header file statements into .hpp files.
- Download or copy the source code into .cpp files and build, using instructions in How to build a shared library file for the C++ Interface on Windows .
- Execute the MATLAB code to build the interface.
- If required, edit the library definition file.
- Execute the MATLAB code to test the functionality.
