Destructors

[prout]

I use my own Matrix class. A function returns a local Matrix-class object I've created in it("Matrix aa;&quot. But before returning it ("return aa;&quot the destructor is called and I return a void object. Then after the return operation the destructor is called again. I don't know why and I thought that the destructor is only called at the end of my function.

It seems like you are returning pointer to local object. The scope of local objects is inside of the function only, they all are destroyed during return from the function.
Use operator "new" for dynamicall allocation of the objects.
