I just bought MATLAB because it is absolutely required at the university I will be attending in the fall. While I've only given MATLAB a quick overview, it seems that it's probably not something I would be able to use for writing papers. It also doesn't look very efficient for quick graphing (since you basically have to code everything). Would it be worth it to also get Mathematica or Maple? Or should I just stick with Open Office Formula editor (what I use now for writing papers with math in them) or a latex editor, and use my TI-89 for graphing? And if Maple or Mathematica is a good complement to MATLAB, is the extra $40 for Mathematica worth it against Maple? Oh, if it matters, I'm an EE major who will probably minor in pure math. Thanks!
