Office hours: MW 1:00pm-1:50pm, W 3:00 - 3:50pm, and by appointment
Lab I:
Dates: Lab I: Thursday Jan 22nd
Place: Engineering Hall rooms 406B1 and 406B8, normal class time (12:00pm-12:50pm)
See
http://www.math.uiuc.edu/iode/materials.html for the Lab I guide.
Lab II:
Dates: Tuesday Feb 3rd
Place: Digital Computer Lab rooms L440 and L520, normal class time (12:00pm-12:50pm)
See
http://www.math.uiuc.edu/iode/materials.html for the Lab II guide.
Grades/Curve: Grades will be based on the percentages below. Curve will be applied if needed.
Quiz: Wednesday, February 11, 10% of your grade.
Exam 1: Thursday, March 19, 20% of your grade.
Exam 2: Tuesday, April 28, 20% of your grade.
Final Exam: Wednesday, May 13, 7-10 PM, 40% of your grade. (Same room as class)
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 http://www.math.uiuc.edu/iode/. 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.
