Debug the package found in the attached Debugging zip folder. You'll find that it's very broken. Its supposed to do matrix multiplication. It mostly just crashes. And if it weren't crashing, it wouldn't be working as advertised. Unzip it, fix it, add appropriate comments, and hand it in. Here's a handy website to test your results: http://www.bluebit.gr/matrix-calculator /matrix- multiplication aspx
