Also, while I haven't done any benchmarks, I believe my version should be faster and definitely simpler than the one present at octave svn (which I checked now, thanks to Jaroslav). If there is interest I can adapt it to be interchangeable with current setdiff. Of course, only after the sparse matrix bug has been sorted out :-) ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
