Doug,

I could not get that to work when multiple output arguments are requested.  My attempt is below.  It’s kind of ugly, maybe someone can come up with a nicer method.

 

Tony

 

function varargout = short(varargin)

  usv = nthargout ([1:nargout()], @short, varargin{:});

   if isa(usv, "cell")

      for i = 1:nargout

        varargout{i} = usv{i};

      endfor

    else

      varargout{1} = usv;

    endif 

endfunction

 

 

 

 

 

 

Here is my testing code that worked:

a=1;
 function q=verylongname(x)
   q(1)={'hi'}
   q(2)={'to you'}
 endfunction
 
 
 
 function [varargout2] = short(varargin)
       varargout = verylongname(varargin{:})
       varargout2=varargout(:)
    endfunction
   
    varargout1=short()
  

put that in an M file and run it.
