Thanks! But I didn't expect this ...

So it returns a syntax error? I meant to provide a simple anonymous
function which returns two outputs ... Maybe this is again the
impossibility to index each expression in Matlab ... so what does it
with these:

octave:1> tp = {1, 1}
tp = 
{
  [1,1] =  1
  [1,2] =  1
}
octave:2> [a, b] = cellfun (@ (x) tp{:}, {1})
error: cellfun: function returned fewer than nargout values
octave:2> a = @ (x) tp{:}
a =

@(x) tp {:}

octave:3> a(5)
ans =  1
ans =  1

?
