William Smith submitted a Comment to Problem 963. We love vectorized solutions. Problem 1 : remove the row average.

I am hoping to stimulate a change to cody where some problems (or all) problems are graded on performance not size. A low size often means an unreadable solution, and people have found enough tricks to make size an irrelevance, anyway.

This is almost exactly the same as my 'reference' solution. But later some other people came up with cleaner solutions...
