I'll see if I can dig up the old benchmarks I wrote looking at it; I'm
pretty sure I tried using both the (i,j) and .at(i,j) methods for
accessing, but I'll have to double-check. In any case, it was pretty much
the same sort of test as the code in my initial email - looping over a
moderate sized matrix, multiplying certain individual elements and
adding. Of course, I may well be overstating the "much"! It's been a couple
of months since I looked at it, IIRC.
