For example if we have <code>+mypackage/myfunc.m</code>, creating a function handle as <code>fh = @mypackage.myfunc</code> won't work.
For example if we have <code>+mypackage/myfunc.m</code>, creating a function handle as <code>fh = @mypackage.myfunc</code> won't work.
As a workaround, we can create an indirection using an anonymous function <code>fh = @(varargin) mypackage.myfunc(varargin{:})</code>.

Similarly for static class methods where <code>fh = @MyClass.myfunc</code> isn't yet supported.

A fuller example is also given below:
<source lang="octave">
classdef method_function_handle_test
 
%  properties
%  end
 
  properties (Hidden, SetAccess = protected)
    hfoo = [];% handle to function
  end
 
  methods
 
    function self = method_function_handle_test ()
      self.hfoo = @foo;   
    end
   
    function bar (self)
        self.hfoo (self);
    end
 
  end
 
  methods (Hidden, Access = protected)
    function foo (self)
      disp ('hello!');
    end
  end
 
end
</source>
Then running:
<source lang="text">
>> x = method_function_handle_test
error: @foo: no function and no method found
error: called from
    method_function_handle_test at line 17 column 17
stopped in <****>/scratch/mfiles/octave_tests/method_function_handle_test.m at line 17
17:      self.hfoo = @foo;
</source>
