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
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.
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 = ':'
