Re: Handling variable number of output arguments in multi-level function calls

Hello Philip, thanks for the answer.

Yes, that seems to be the case. I have just found
http://stackoverflow.com/questions/4895556/how-to-wrap-a-function-using-varargin-and-varargout
with an example of how to do it.

As a side-note, I think there is a small Matlab/Octave compatibility 
issue here. Following the solution provided by SCFrench (who works for 
The MathWorks) I do the following test in Octave:
--->
octave:75> function varargout = wrapper( varargin )
> [varargout{1:nargout}] = sin( varargin{:} );
> endfunction
octave:76> wrapper(0)
octave:77> a=wrapper(0)
a = 0
octave:78> sin(0)
ans = 0
<---
So I guess this solution does not work in Octave as in Matlab when the 
outer-most function is called with no output arguments. I cannot 
double-check in Matlab, as I do not have it. Can somebody please 
confirm? If so I can then file a report.

Regards,
José.
