Use enumerations to represent a fixed set of named values, where all the values are of the same kind. You can derive enumeration classes from other classes, such as built-in numeric types. The enumeration members then inherit arithmetic and ordering operations of the superclass.
enumeration | Display class enumeration members and names |
isenum | Determine if variable is enumeration |
meta.EnumeratedValue | Describe enumeration member of MATLAB class |
Associate values with predefined names using constant properties or enumeration classes.
Define enumeration classes by creating an enumeration
block in the classdef file.
Refer to enumeration members using the class name and the member name.
Use logical, set membership, and string comparison operations on enumerations.
Enumeration Class Restrictions
Enumeration classes restrict certain aspects of their use and definition.
Mutable Handle vs. Immutable Value Enumeration Members
Use a handle enumeration to enumerate a set of objects whose state can change over time. Use a value enumeration to enumerate a set of abstract (and immutable) values.
The type of enumeration class determines the information MATLAB® saves with the class.
Enumerations Derived from Built-In Types
Enumeration classes derived from built-in types inherit behaviors from these types
Enumerations That Encapsulate Data
Define properties in an enumeration class to associate specific data with enumeration members.
Enumerations for Property Values
Use enumeration classes to restrict properties to a predefined set of values.
