Class Building Blocks

MATLAB organizes class definition code into modular blocks, delimited by keywords. All

keywords have an associated end statement:

• classdef...end — Definition of all class components


• properties...end — Declaration of property names, specification of property
  attributes, assignment of default values


• methods...end — Declaration of method signatures, method attributes, and function
  code


• events...end — Declaration of event name and attributes


• enumeration...end — Declaration of enumeration members and enumeration
  values for enumeration classes.

properties, methods, events, and enumeration are keywords only within a

classdef block.

Class Definition Block

The classdef block contains the class definition within a file that starts with the

classdef keyword and terminates with the end keyword.
