saturday night fever

So for the past day and a half I have been working on my Numerical Linear Algebra homework. I just couldn't understand what the problem was really asking. As I was getting ready to give up and e-mail the prof to whine about my stupidity I realized that the assignment had changed since I printed it off. I was actually working on a wrong problem. Oh man, how much I hate stuff like this. I hope tomorrow I'll get this done asap and start a new calculation for my senior thesis. Good night for now.
