Applied Linear Algebra and Numerical Analysis

Important Announcements and Useful Hints

• 3/14/03: The m-files for the pendulum problem discussed in class today are posted in the pendulum directory. The graphics I showed of aerodynamic simulations came from a NASA website. Nice simulations of other fluid flow problems can be found on the web at various sites, for example the NCAR website (National Center for Atmospheric Research).

• 3/12/03: Review session Tuesday March 18, 5:00 - 6:30pm in GUG 410.
  Office hours: Marica Pelanti Monday 3/17 and Wednesday 3/19, 3:30 - 5:00
  I will have office hours Tuesday and Wednesday 10-11 and Wednesday 1:30-2:30, or by appointment.

• 3/12/03: Correction to HW 8 #4(a) and (d): The expression given for Iexact is wrong! It should involve erf(50) and erf(40) instead of erf(5) and erf(4). Also the factor sqrt(pi)/10 should be sqrt(pi)/20.

• 3/5/03: Another Correction to HW 7, #4(f). The second displayed equation should read
  P_1'(x_2) = f'(x_2) - 1/2 h f''(x_2) + O(h^2)
  (The first h^3 on the assignment should be h^2)

• 3/4/03: Correction to HW 7, #4(f). The second displayed equation should read
  P_1'(x_2) = f'(x_2) - 1/2 h f''(x_2) + O(h^3)
  (The first + on the assignment should be -)

• 2/24/03: Midterm #2 is Friday 2/28. There will be a review session Wednesday 2/26 3:30--5:00 in Guggenheim 410. Our office hours will be in GUG this week rather than the MSCC lab. I will have different office hours than usual this week:
  Tuesday 3:30 - 4:30, Wednesday 1:30-2:30, Thursday 9-10 and 3-4, and no office hours Friday.

• 2/8/03: I will be out of town at a SIAM conference Monday 2/9 through Thursday 2/12. Marica Pelanti will lecture Monday and Wednesday, and will also be available during my office hours on Wednesday at 1:30 (at her Guggenheim office) and Thursday 9-10 (at the MSCC lab). I will be at MSCC for my Friday 9-10 office hours. I should be responding to email if problems arise during the week.

• 2/2/03: Midterm #2 is now scheduled for Friday, February 28 (instead of February 26 as originally announced).

• 1/28/03: The first midterm is Friday 1/31. There will be review sessions Wednesday 1/29 at 3:30 and 5:30 in Guggenheim 410.

• 1/28/03: Office hours this week will be in our Guggenheim offices instead of the MSCC lab since there is no homework due.

• 1/10/03: See the B-022 schedule on the MSCC lab webpage for the "Matlab help desk" schedule, currently Thursday 3:30-5:30 and Friday 11:30-1:30. These are the hours Bela Frigyik will be in the lab, a grad student who can also help with homework questions. (This week and next he is out of town and Mariana Carrasco Teja will be there instead.)

• 1/8/03: Correction on HW1 #4(b). Please replace sin(x) by sin(8x).

• 1/6/03: There will be two introductory sessions in the MSCC lab this week: Tuesday 1/7 at 4:30pm and Thursday 1/9 at 12:30pm, in CMU B027. I will demonstrate how to use some basic features.
