varargout.
This special keyword indicates that the number of return values
is variable.  The general syntax for a function that returns
a variable number of outputs is
function [out_1,...,out_M,varargout] = fname(in_1,...,in_M)
The function is responsible for ensuring that varargout is
a cell array that contains the values to assign to the outputs
beyond out_M.  Generally, variable output functions use
nargout to figure out how many outputs have been requested.
     varoutfunc.m
function [varargout] = varoutfunc
  switch(nargout)
    case 1
      varargout = {'one of one'};
    case 2
      varargout = {'one of two','two of two'};
    case 3
      varargout = {'one of three','two of three','three of three'};
  end
Here are some examples of exercising varoutfunc:
--> [c1] = varoutfunc c1 = one of one --> [c1,c2] = varoutfunc c1 = one of two c2 = two of two --> [c1,c2,c3] = varoutfunc c1 = one of three c2 = two of three c3 = three of three
