Update of bug #36606 (project octave):

              Item Group:        Incorrect Result => Documentation          
                  Status:                    None => Fixed

Follow-up Comment #1:

In 3.2.4, The doc string for union says


 -- Function File: [C, IA, IB] = union (A, B)
     Return index vectors IA and IB such that `a == c(ia)' and `b ==
     c(ib)'.


so you are correct that the result you see does not match the documentation. 
However, the function is correct (and compatible with Matlab) and the
documentation is wrong.  In the current version of Octave (3.6.x): the
documentation says


 -- Function File: [C, IA, IB] = union (A, B)
     Return index vectors IA and IB such that `a(ia)' and `b(ib)' are
     disjoint sets whose union is C.


which I think is correct.  So I'm closing this report and marking it as a
documentation bug that has been fixed.
