MATLAB Object-Oriented Programming

This subsref enables the use of dot notation to create a plot using the name 'plot'.

The statement:

obj = MyPlot(1:10,1:10);

h = obj.plot;

calls the plot function and returns the handle to the graphics object.

You do not need to code each method and property name. The otherwise code in the

inner switch block manages any name reference that you do not explicitly specify in

case statements. However, using this technique exposes any private and protected class

members via dot notation. For example, you can reference the private property, x, with

this statement:

obj.x

ans =

1 2 3 4 5 6 7 8 9 10

The same issue applies to writing a subsasgn method that enables assignment to private

or protected properties. Your subsref and subsasgn methods might need to code each

specific property and method name explicitly to avoid violating the class design.
