Homework: Assigned every week. Worth 10%, possibly spot checked (spot checked means: some spot(s) of each homework checked, and all will be collected). Lowest homework grade dropped. Some homework will be iode based (see below).

Iode: Iode is a free software package tailored for this course. We will spend some time in the computer lab learning this software and you will be assigned some homework using it. See Iode requires Matlab or Octave (version 2 works for sure, version 3 maybe). Matlab is available in the lab and Octave is free so you need not purchase anything.

Test Policies: No books, notes, calculators or computers allowed on the exams or the final.
