Enumeration Classes with Properties

Enumeration classes can define properties to store data values. The enumeration

members represent specific values for these properties, which MATLAB assigns in the

class constructor. For information on defining enumeration classes, see “Define

Enumeration Classes” on page 14-5.

Store Data in Properties

NoteEnumeration classes that subclass built-in numeric or logical classes cannot define

or inherit properties. For more information on this kind of enumeration class, see

“Enumerations Derived from Built-In Types” on page 14-28.

Define properties in an enumeration class if you want to associate specific data with

enumeration members, but do not need to inherit arithmetic, ordering, or other

operations that MATLAB defines for specific built-in classes.

Representing Colors

Define an enumeration class to represent the RGB values of the colors in a color set. The

Colors class defines names for the colors, each of which uses the RGB values as

arguments to the class constructor:

classdef Colors

properties

R = 0

G = 0

B = 0

end

methods

function c = Colors(r, g, b)

c.R = r; c.G = g; c.B = b;
