Can any one tell me why the following DLD function prints a row vector
but returns a column vector?   I think it should print and return a
column vector.  Can you also tell me how I can return a Row vector
instead of a column vector?   

rowvec_test.cc
-------------------------------------------------------------------
#include <octave/oct.h>
#include <octave/pager.h>

DEFUN_DLD(rowvec_test,args, , "\nRow vector test\n"){

  RowVector the_row = args(0).vector_value();
  octave_stdout << "The Row vector = \n" << the_row << "\n";
  return octave_value(the_row);
}
-------------------------------------------------------------------

Run it from octave like this:

v = [ 1 2 3];
rowvec_test(v)

Thanks.
