Using C++ would be best for QucsStudio, of course, but Python could be okay, too. Up to now, QucsStudio has no Python interface. Do you know how such an interface looks like? Can you help here?
Implementing MoM would be fantastic indeed! Can you explain how this should look like, e.g. what part should be performed by QucsStudio and what by Python? What packages will you use? Have you already examples etc.?
