SUBSREF Array Dereferencing

Section: Array Generation and Manipulations

Usage

This function can be used to index into basic array types (or structures). It provides a functional interface to execute complex indexing expressions such as a.b(3){5} at run time (i.e. while executing a script or a function) without resorting to using eval. Note that this function should be overloaded for use with user defined classes, and that it cannot be overloaeded for base types. The basic syntax of the function is:

   b = subsref(a,s)

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

type is a string containing either '()' or '{}' or '.' depending on the form of the call.
subs is a cell array or string containing the the subscript information.

When multiple indexing experssions are combined together such as b = a(5).foo{:}, the s array should contain the following entries

  s(1).type = '()'  s(1).subs = {5}
  s(2).type = '.'   s(2).subs = 'foo'
  s(3).type = '{}'  s(3).subs = ':'
