When @var{a} is a class object ## defined with a class constructor, then @code{subsindex} is the ## overloading method that allows the conversion of this class object to ## a valid indexing vector. It is important to note that ## @code{subsindex} must return a zero-based real integer vector of the ## class @qcode{"double"}. For example, if the class constructor ## ## @example ## @group ## function b = myclass (a) ## b = class (struct ("a", a), "myclass"); ## endfunction ## @end group ## @end example ## ## @noindent ## then the @code{subsindex} function ## ## @example ## @group ## function idx = subsindex (a) ## idx = double (a.a) - 1.0; ## endfunction ## @end group ## @end example ## ## @noindent ## can then be used as follows ## ## @example ## @group ## a = myclass (1:4); ## b = 1:10; ## b(a) ## @result{} 1 2 3 4 ## @end group ## @end example ## ## @seealso{class, subsref, subsasgn} ## @end deftypefn function idx = subsindex (a) error ("subsindex: not defined for class \"%s\"", class (a)); endfunction
