SUBSREF Overloaded Class Indexing

Section: Object Oriented Programming


This method is called for expressions of the form
  c = a(b), c = a{b}, c = a.b

and overloading the subsref method allows you to define the meaning of these expressions for objects of class a. These expressions are mapped to a call of the form

  b = subsref(a,s)

where s is a structure array with two fields. The first field is

When multiple indexing experssions are combined together such as b = a(5).foo{:}, the s array contains the following entries
  s(1).type = '()'  s(1).subs = {5}
  s(2).type = '.'   s(2).subs = 'foo'
  s(3).type = '{}'  s(3).subs = ':'
