You have defined a class derived from a parent class with a constructor. There is a constructor in the derived class. MATLAB implicitly runs the constructor of parent class and I do not want in my case. How can I avoid MATLAB implict superclass constructor call? Help me out.

You cannot avoid the superclass constructor being called (explicitly or implicitly) from the subclass constructor. From the documentation: "If you do not make an explicit call to a superclass constructor from the subclass constructor, MATLAB makes the implicit call when accessing the object."

If you don't want your subclass constructor to call the superclass constructor, are you sure that you want the subclass to inherit from the superclass?

Can you explain in more detail what your superclass and subclass represent? It's possible that inheritance is not the right tool for your class hierarchy.

If you want something that walks like a duck, quacks like a duck, and swims like a duck but isn't a duck, it shouldn't inherit from the duck class.
