Details:

Environment:
 * Octave 3.2.4_gcc-4.4.0
 * Windows

Error:
When "[c,ia,ib]=intersect(a,b,'rows')" function calculates the ib indexes
(line 76 in intersect.m), it doen't distinguish between column or rows, as it
uses length(a).

Fix:
Changing line 76:

      ib = jb(ic(ii+1) - length (a));   ## b(ib) == c

To

      if (nargin > 2)
        ib = jb(ic(ii+1) - size (a, 1));   ## b(ib) == c
      else
        ib = jb(ic(ii+1) - size (a, 2));   ## b(ib) == c
      endif

takes into account the 'rows' input parameter, so the right dimenson is used.
