If I use this:<p><a href="http://www.mathworks.com/matlabcentral/fileexchange/18798-timeit-benchmarking-function" rel="nofollow">http://www.mathworks.com/matlabcentral/fileexchange/18798-ti...</a><p>which warms up the function, averages over repetitions and tries to account for various overheads, the ratio states about the same (1:1.5 ish). I would normally use timeit(), but for a quick post, I was being sloppy.
