Method Attributes

Attribute

Name

Class Description

Abstract logical Default =

false

If true, the method has no implementation. The method has

a syntax line that can include arguments that subclasses use

when implementing the method:

• Subclasses are not required to define the same number of
  input and output arguments. However, subclasses
  generally use the same signature when implementing their
  version of the method.


• The method can have comments after the function line.


• The method does not contain function or end keywords,
  only the function syntax (e.g., [a,b] = myMethod(x,y))
  Access • enumeration,
  default =
  public


• meta.class
  object


• cell array of
  meta.class
  objects

Determines what code can call this method:

• public — Unrestricted access


• protected — Access from methods in class or subclasses


• private — Access by class methods only (not from
  subclasses)


• List classes that have access to this method. Specify
  classes as meta.class objects in the form:
  
  
  • A single meta.class object
  
  
  • A cell array of meta.class objects. An empty cell
    array, {}, is the same as private access.
  
  
  
  

See “Class Members Access” on page 12-28

Hidden logical Default =

false

When false, the method name shows in the list of methods

displayed using the methods or methodsview commands. If

set to true, the method name is not included in these listings

and ismethod does not return true for this method name.

Sealed logical Default =

false

If true, the method cannot be redefined in a subclass.

Attempting to define a method with the same name in a

subclass causes an error.
