When you refer to an enumeration member, the constructor initializes the property

values:

e = SyntaxColors.Error;

e.R

ans =

1

Because SyntaxColors is a value class (it does not derive from handle), only the class

constructor can set property values:

e.R = 0

You cannot set the read-only property 'R' of SyntaxColors.

For more information on enumeration classes that define properties, see “Mutable Handle

vs. Immutable Value Enumeration Members” on page 14-34.

Enumeration Class Constructor Calling Sequence

Each statement in an enumeration block is the name of an enumeration member,

optionally followed by an argument list. If the enumeration class defines a constructor,

MATLAB calls the constructor to create the enumerated instances.

MATLAB provides a default constructor for all enumeration classes that do not explicitly

define a constructor. The default constructor creates an instance of the enumeration

class:
