Import large C++ project into Matlab

I have a C++ console application with lots of classes, and external dependencies, and I want to integrate it with Matlab project.

So, I have built the C++ project as DLL, but I don't get how to continue. I have tried just to call loadlibrary() giving the .dll filename.

Please, help to understand what to do next.

Do you have a header file with all of the exported function prototypes? Do all of your functions use the extern "C" interface?

No, I don't have. I am actually first time making dll. I have just set Configuration Properties->General->Configuration type to Dynamic library in Visual studio.

If you look at the documentation for loadlibrary, you will see that you need to feed it a header file that has all of the exported function prototypes in it, and that those functions must use the extern "C" interface.
