There are, here at Cody, a lot of people who can code very well on Matlab. But I find that every one who publish a problem should have the humility to wait for many solvers before he/she put his/her own solution. But that's only my personal opinion. ;-)
You can't see my solution until u make working one with the same size, so I think it doesn't matter.
