The end of Matlab
That depends on what you want evens() & last(5) to mean. Does that mean the last 5 evens (returning 5 values) or the values in the last 5 that are also even items (returning either 2 or 3 values depending on if the structure has an odd or even number of elements). It could be interpreted either way. Your subset below does the first, the other examples do the 2nd. -- Gregory (Greg) L.

evens() & last(5)
wouldn't x[evens()][last(5)] do the & already? or is different, though. Claudia -- Claudia Beleites Dipartimento dei Materiali e delle Risorse Naturali Universit? degli Studi di Trieste Via Alfonso Valerio 6/a I-34127 Trieste phone: +39 (0 40) 5 58-34 47 email: cbeleites at units.it
