Inside a class method (which as I said above is a function) you can access private properties as well. Abstract classes help to build similar classes which can use the same interface. Then the subclass adds code to display the subclass part of the object: If you create a subclass object, MATLAB calls the superclass constructor to initialize the superclass part of the subclass object. Okay so what I take from this is the fact that there are static methods, but no 'static objects'. attribute. MathWorks is the leading developer of mathematical computing software for engineers and scientists.
