MATLAB: Get maximum number of outputs from anonymous function

anonymous functionvarargout

Hi everybody. I would like to call a function from within another function. The problem is that i don't know a-priori the number of output variable of the function i'm calling. I can evaluate it with nargout, but once i've done it, how can I call the function with that number of outputs?
function varargout = myfunction(fun, varargin)
   % Do some stuff here

   funName = func2str(fun);
   maxnargout = nargout(funName);
   [??] = fun(varargin{:})
   % Do some stuff here
Using "eval" I could do something like
eval(['[ varargout{1}' sprintf(', varargout{%i}',2:maxnargout ) '] = fun(varargin{:})'])
but it is utterly awful!!!!

Hello Luca,
That's a somewhat tricky one, and I agree that going the "eval" route is not the best way. You can get around it using some tricks with cell arrays. Also, I believe that you can use nargout directly on the function handle.
f = @max;
x = rand(3);
results = cell(1, nargout(f));
[results{:}] = f(x);
