Deploy to C++ Applications Using mwArray API (C++03)

Integrate packaged MATLAB® functions into C++ applications using the mwArray API for data exchange

In this approach, you create a C++ shared library and header file from MATLAB functions you want to deploy. Use the legacy MATLAB Compiler SDK™ API for C++ as an interface between the C++ application and the deployed MATLAB functions. Use the mwArray API to handle data exchange between the C++ application and the deployed MATLAB functions. You must include the generated header file in your C++ application using a preprocessor directive for the deployed MATLAB functions to be available as member functions within your C++ code. You need to explicitly manage the life-cycle of the MATLAB Runtime instance used by the deployed MATLAB functions. The runtime instance can be run only in-process with the C++ application and deployed MATLAB functions can be executed only synchronously.

The C++ mwArray API supports only C++03 functionality. C++ shared libraries that use the mwArray API have an interface that uses C-style functions to initialize the MATLAB Runtime, load the packaged MATLAB functions into the MATLAB Runtime, and manage data that is passed between the C++ driver code and MATLAB Runtime. These functions are described under C/C++ API. The functions listed under C++ mwArray API are specific to the mwArray API and cannot be used for shared libraries created for other APIs.
