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>. | 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. | 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"> | |||

properties (Hidden, SetAccess = protected) | |||

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 | |||
