Cube.m

classdef Cube < Square

 

 % properties are not needed

 

 methods

 function obj = Cube(s)

 if nargin == 0

 s = 1;

 end

 obj@Square(s)

 end

 

 function out = volume(obj)

 out = obj.side ^ 3;

 end

 

 function disp(obj)

 fprintf('The cube has volume %.1f\n', volume(obj))

 end

 end

end

>> mys = Square(3)

mys = 

The square has side 3.00

>> mys.area

ans =

 9

>> myc = Cube(4)

myc = 

The cube has volume 64.0
