MATLAB call compiled MCC program

We have a customer who has delivered some code, developed in MATLAB and compiled with mcc. They won't give uncompiled m code before you ask! Some of the functions are in shared libraries (this is their API), such that they can be called from a C++ or .NET and the system can be automated.

We would like to develop the automation in MATLAB, calling the mcc compiled functions directly from MATLAB.

1) Is this possible using mex (https://www.mathworks.com/help/matlab/write-cc-mex-files.html) or could it create some run time conflict?

2) Will wrapping the C++ library in a dot NET library, then calling the dot NET library from MATLAB help?

Hi,

unfortunately both will not work. The compiled code will need to run an instance of the MATLAB Compiler Runtime (MCR), but this can't run inside MATLAB itself. The only way would be to use remoting (see here) , so having a separate process.

Understood. Remoting sounds messy!

Would another option be, to build a set of command line executables in C++ or .NET for example - calling the API - and writing the results to a file. Then call these interim executables from the command line within MATLAB using 'system()'?

One viable option is to write a simple C/C++ daemon, which will load the compiled library (see Integrate a C/C++ Shared Library into an Application ) and provide some kind of RPC interface to the desired library functions. You will then use MATLAB's "udp" or "tcpclient" commands to talk to this daemon and call commands from the library.
