Details:

I am writing this because there is a discrepancy between how length() works in
Octave and how it works in m-files. This might be intentional, but I still
wanted to bring it up. 


#include <octave/oct.h>

DEFUN_DLD (wrng, args, ,"" )
{
  octave_value_list retval;
  Matrix a (5,2);
  retval(0) = a.length();
  return retval;
}


In the spirit of how Octave interprets length () in function wrng() that is
above should return 5, but in fact it return 10 (all of the elements of 'a').
