for C++: Can I use MATLAB ENGINE (matlab::engine) with CTF (matlab::cpplib), for matlab 2019b?

it seems to be that

#include "MatlabEngine.hpp"

and

#include "MatlabCppSharedLib.hpp"

cannot co-exist?

If I include matlab engine first, I cannot use ctf file. If I include cpp shared lib first, I cannot use engine.

Is there any solution to this issue for matlab 2019b?

The reason/driving factor is behind this need -- I want to be able to switch (only once at program start up) between using matlab engine or ctf based on user input. Any other suggestion or alternative ways to achieve this goal will be greatly appreciated.

It is my understanding that you are not able to use #include "MatlabEngine.hpp" and #include "MatlabCppSharedLib.hpp" within the same “cpp” file.

As a workaround to this issue, I would suggest you create two separate "cpp" function files, one that exclusively includes "MatlabEngine.hpp", and another that exclusively includes "MatlabCppSharedLib.hpp".

You can then have one or the other called in the main function based on the user's input.

Thanks! I was hoping to avoid this alternative, since the feval calls are the same, I'd have to copy and paste same calling codes into two different "cpp" files and have to remember to update them separately. Unless there is some macro that can help with this separate maintainability issue?

Regarding using macros, the preprocessor only does one pass through everything, so I don't believe it’s possible.
