ah, no! code 1 was *faster* under matlab! the ratio is 0.19:1

i find this result quite staggering.

on my laptop, octave (3.0.5) takes 200 secs for the first code and
just 24 secs for the second--i thought i had proved my point.

A ratio of 8.3:1

however, on the department server (admittedly a much faster machine),
matlab ground through the first code in 0.82 secs while the second
code took 4.3 secs.

A ratio of 5.2:1.  Not quite the same, but I think the point is proven
