How to convert C++ simulations to Simulink?

Hello,

so I have a 6DOF simulation of an aircraft. There are a few header files eg: 1. class_heirarchy.hpp -> three classes (base class, one instance of inherited class, the second inheritance of a derive class) 2. global constants.hpp 3. global_header.hpp 4. utility_header.hpp

and in the source files i have the actual simlation wherein i have the following cpp files: kinematics.cpp environment.cpp aerodynamics.cpp propulsion.cpp ins.cpp control.cpp actuator.cpp forces.cpp newton.cpp euler.cpp execution.cpp in each of these .cpp files there is a _def() function (defines the variables that are part of that module), a _init() function that initialises the values at the start of the simulation and then the actual function/functions that actually run when the simulation is going on. so the def and the init functions only get called once at the start of the simulation.

so now i have implemented my baseline controller in C++. what i need to do now is implement an adaptive controller. I would like to do this in MATLAB/SIMULINK. Is there an easy way (i understand its not particularly easy) but i mean an understandable way to get my 6DOF simulation into MATLAB so that i dont need to reimplement the whole model. I hope i have made my question clear.

No need to dumb it down .... I have looked at mex and all that .. and havent really understood what is going on there ..

Thanks and regards,

Sanchito

To bring C++ code into Simulink, you need to create a C-MEX S-function wrapper so that it can be used like any other S-function block in a model. Please see Integrate C Functions Using Legacy Code Tool to automatically generate the C-MEX S-function wrapper.
