Build C++ MEX Programs
Build your C++ MEX application using the MATLAB®
mex to set up your environment and
compile the C++ source code.
Use compilers that support C++11. For an up-to-date list of supported compilers, see the Supported and Compatible Compilers website.

If you have installed one of the supported compilers, set up the compiler for C++
MEX applications using the
mex command. When provided with an
option to select a compiler, select an installed compiler that the MATLAB C++ MEX supports.
mex -setup C++

MEX Include Files
Include the following header files in your C++ source code. Header files contain
function declarations with prototypes for the routines that you access in the API
libraries. These files are in the
and are the same for Windows®, Mac, and Linux® systems. C++ MEX files use these header files:
mex.hpp— Definitions for the C++ MEX API
mexAdapter.hpp— Utilities required by the C++ MEX function operator
mexAdapter.hpp only once with the
MexFunction class definition in MEX applications that
span multiple files.
MEX files are platform-specific. MATLAB identifies MEX files by these platform-specific file extensions.
