Rutgers University SOE 14:440:127 Lecture 12 Reminders / Updates Exam 2 grading- getting close to done. We’re aiming for Thursday, but count on getting the scores on Friday. I will be here this weekend if people want to talk things over. Final grade will be curved if you did your problem sets. Emails Project 2 is out.- Due Dec 7 th Let me know if you have questions. Not too hard (analysis/animation). Project 3 will be out soon- Due December 13th Engineering Options, Fun Options. You’ll use GUIs for these. NEXT WEEK- No lecture, no recitation . Monday and Tuesday recitations meet the following week. Topics this week are mostly not in the book again. Week after next- Review for the final. Then you have your final. Then one final lecture on general computing skills (Unix/Linux, How to use what you know from Matlab in other languages, Free software, Databases, Stories from Industry)
Rutgers University SOE 14:440:127 Lecture 12 Numerical Calculus- Derivatives Estimates Derivative is dy/dx … which is Δ y ./ Δ x diff(y) ./ diff(x) Example: x = 0:0.1:10; y = x.^2; slope = diff(y) ./ diff(x)
