I need to create simple COM object, or some other thing that will receive data (matrixes) run calculations and give back results (also matrixes). Is it possible to achive this by some simple means?

You can create a working starter project that creates a simple COM object using the COM/ATL project wizards in Visual C++. File->New->Project, then select project type "Visual C++ Projects", "ATL", "ATL Project". Then right-click the new project in the class view, select Add->Add Class. Then select the "ATL" category, and select "ATL Simple Object". Fill in names for your object and there you go, you have a working COM object.
