Brian,
I just reran
>> tic;nim_minimax;toc
ans = 4.2462
...a lot more than I was getting earlier today at 3.7
when I disabled the "all" timestamp check
the time dropped down to...
ans = 4.1870
which is quite a small change.
You should still look at doing *ONLY* matrix math and get
rid of all of your "for - loops"
