Just to clarify slightly, the "for" command in Octave loops over each of
the list elements (remember that [1:6] expands to [1 2 3 4 5 6]) so
there is no need to increment the counter as you would in other
languages such as C or Fortran.

I've always though the manual index was fairly comprehensive. Anyway,
assuming that you are using info to view the manual (I think you said
that you use emacs), you can get to the right spot by searching for
"product" - it will take you to the "Sums and Products" node in the
"Arithmetic" section.

The function index is also a pretty useful place to search for relevant
terms. Of course, familiarity with the manual helps, as does subscribing
to this list.
