If not, the second argument is converted to the basis used by the first argument. We then check that the powers are the same. If not, they can't be added. Finally, after conversion, both arguments have the same basis and powers, so their numerical values can simply be added. Please give it a try and let me know if you find it useful.
Inheritance is another important aspect of object-oriented programming.
The LTI object, which is used by several of the control toolboxes to manipulate Linear Time-Invariant systems of ordinary differential equations, provides an example of inheritance. The LTI object itself is known as the base class . It carries out operations that are independent of any particular representation of the system. Bode plots and Nichols charts are LTI methods. Detailed operations that depend upon a particular representation are done by the derived classes .
