How to Create Enumeration Instances

When you first refer to an enumeration class that derives from a built-in class such as,

int32, MATLAB passes the input arguments associated with the enumeration members

to the superclass constructor. For example, referencing the Second Results member,

defined as:

Second (50)

means that MATLAB calls:

int32(50)

to initialize the int32 aspect of this Results object.

How to Alias Enumeration Names

Enumeration classes that derive from MATLAB built-in numeric and logical classes can

define more than one name for an underlying value. The first name in the enumeration

block with a given underlying value is the actual name for that underlying value and

subsequent names are aliases.

Specify aliased names with the same superclass constructor argument as the actual

name:

classdef Bool < logical

enumeration

No (0)

Yes (1)

off (0)

on (1)

end

end

For example, the actual name of an instance of the Bool.off enumeration member is No:

a = Bool.No
