If you downloaded the contest code from the File Exchange before 9PM EDT, be sure to get the updated version. There was an error in grade.m, first pointed out by Alan Chalker on the newsreader thread. You may remember Alan as the winner of the last MATLAB Contest, Blockbuster. You can read about him and his last contest experience. We’re happy to see the entries that have been submitted so far and especially welcome the new participants. The contestant who submits the best entry before the end of darkness at noon EDT on Thursday will join Alan in the MATLAB Contest Hall of Fame.
Thanks Alan for pointing out the mistake! I doubt that anybody would have been able to locate it :-)
