I'm calling matlab optimization function through matlab engine by "eval" from visual studio (C++) and I want to get the result. For that I need to know when matlab finishes, wait for it from the C++ project and resume afterwards. I found only documentation about how to do it from Python:

Is there a C++ equivalent?

There are MATLAB Engine APIs for C which should work in C++ environment:

The C version of MATLAB Engine does not support the asynchronous mechanism in Python Engine.

The execution is normally synchronous: waiting for it to finish is what normally happens.

MATLAB Engine APIs for C is synchronous by default, which is exactly what you want: "wait for a matlab function called from C++ to finish before proceeding to the rest of my code".
