Assume that the user-defined function GetComApp.m has access to a COM object defined in the pseudo-class ComNamespace.ComClass. One of its methods is readData, with the signature:

System.String RetVal readData(ComNamespace.ComClass this, System.String strIn)

The input argument is defined in the pseudo-class NetDocTest.MyClass, which has a property named MyApp.

function GetComApp(obj)
comObj = ComNamespace.ComClass;
obj.MyApp = comObj;
% To pass a COM object to another process, lock the object
NET.disableAutoRelease(comObj);
end

The example in NET.enableAutoRelease shows how to call the GetComApp function.
