Matlab On Ubuntu

I freaking hate that the Windows shortcuts aren’t emulated in Linux. WTF. It’s like a reflex to use them in Linux. I’m always surprised when I save a file with CTRL+S it doesn’t save. CTRL+X, CTRL+V don’t work either. WTF.

I must have wasted 10 minutes on shit like that this afternoon while I was programming some numerical integrals with the Simpson 1/3 method. This method is of the 4th [O(h^4)] order. We used a Richardson Extrapolation to gain two more magnitudes of order. Time matters when you are doing a 45 minute lab and that at the end of the lab, you have to hand in your programs.

We spent another 20-25 minutes trying to figure out what the problem was with our program. We had some syntax errors. The if statement had the semi-colon at the wrong place. Otherwise, I would have finished this lab in about 20 minutes flat.

My partner was sick, so I was stuck doing most of it myself. He was in class, but his frequent trips to the bathroom weren’t helping him do any coding.
