MATLAB Object-Oriented Programming

copy the data stored in the object properties. The copy refers to the same object as the

original handle. If you change a property value on the original object, the copied handle

references the same change.

Handle Object Behavior

Here is a handle class that stores a value in its Number property. The default property

value is the number 1.

classdef NumHandle < handle

properties

Number = 1

end

end

Create a NumHandle objects assigned to the variable a.

a = NumHandle

a =

NumHandle with properties:

Number: 1

Assign the value of a to another variable, b.

b = a

b =

NumHandle with properties:

Number: 1

The variables a and b refer to the same underlying object. Changing the value of the

Number property of a also changes the Number property of b. That is, a and b refer to the

same object.

a.Number = 7

a =

NumHandle with properties:
