How to Specify Attributes and Superclasses

The classdef block contains the class definition. The classdef line is where you

specify:

• Class attributes


• Superclasses

The classdef block contains the properties, methods, and events subblocks.

Class Attribute Syntax

Class attributes modify class behavior in some way. Assign values to class attributes only

when you want to change their default value.

No change to default attribute values:

classdef ClassName

...

end

One or more attribute values assigned:

classdef (attribute1 = value,...)

...

end

For example, the TextString class specifies that it cannot be used to derive subclasses:

classdef TextString (Sealed)

...

end
