COM Objects in MATLAB
The Microsoft® Component Object Model (COM) provides a framework for integrating reusable, binary software components into an application. Because components are implemented with compiled code, the source code can be written in programming languages that support COM. Upgrades to applications are simplified, as components can simply be swapped without the need to recompile the entire application. In addition, a component's location is transparent to the application, so components can be relocated to a separate process or even a remote system without having to modify the application.
Alternatively, consider using the Microsoft .NET Framework.
MATLAB supports COM and the .NET Framework integration on the Microsoft Windows® platform only.
