I try to keep the examples short -- and the computation of a realistic
example is a bit involved -- so rather than post the code to compute the
example, here's an octave saveset with a realistic example, and a modified
"looptest.m" that reads it and runs the timing comparison.

Thanks,
Dave Cottingham
