MATLAB Object-Oriented Programming

function obj = SimpleHandleClass(c)

if nargin > 0

obj.Color = c;

end

end

end

end

Create an instance of SimpleHandleClass, assigning a value of red to its Color

property:

obj = SimpleHandleClass('red');

Pass the object to the function g, which assigns blue to the Color property:

y = g(obj);

The function g sets the Color property of the object referred to by both the returned

handle and the original handle:

y.Color

ans =

blue

obj.Color

ans =

blue

The variables y and obj refer to the same object:

y.Color = 'yellow';

obj.Color

ans =

yellow

The function g modified the object referred to by the input argument (obj) and returned

a handle to that object in y.
