Wednesday MATLAB exercise and reminder about Thursday's class

MATLAB exercise: Use the zeros and ones commands to make a vector containing 100 zeros and another vector containing 50 ones. 

Reminder: On Thursday, class will first meet in the classroom in the M Building, then later move to the computer lab.

Friday MATLAB exercise

Define A to be a 10x10 identity matrix. Find the eigenvalues of A, 2*A, and A^2. Explain what you see.

Wednesday MATLAB exercise and reading for lecture 4

Reading for Lecture 4:

CC Pt. 7.1-7.2 (p. 697-703) Ordinary differential equations

CC 4.1 (p. 78-83) Taylor series

CC 25.1 (p. 707-715) Euler’s method

MATLAB exercise: Define x = linspace(0,10,5) and then y = sin(x) and z = sqrt(x) and understand what operations have been used in defining the elements in y and z.

Tuesday MATLAB exercise and sample exam problems

MATLAB exercise: Find out what the linspace command does. Generate a vector with five elements spaced equally between 0 and 10.

Sample exam problems: The first exam in this class is next Tuesday (May 29). A set of sample exam problems has been posted on T-Square. We will discuss these sample problems in class on Thursday. You will get much more out of this discussion if you have worked through the problems on your own before class.

Monday MATLAB exercise and minor homework correction

Correction to HW 1: The file names for the two MATLAB files you turn in should be HW1Prob1LastName.m and HW1Prob2LastName.m. The assignment originally listed these file names as HW2Probx... The homework assignment on T-Square has been updated.

MATLAB exercise: Create two row vectors with three elements by typing x = [1 2 3] and y = [2 1 0]. Evaluate z = x + y and understand what this quantity is.

Reading for lecture 3 and Friday MATLAB exercise

Reading for Lecture 3:

CC 9.1.2 Singular matrices

CC 10.2 Matrix inverse (skip Example 10.3)

CC 10.3 Ill conditioned matrices

Eigenvalues – excerpt from Greenberg available from T-square Resources

MATLAB exercise:
Calculate y = sin^2(x) for x = 30, 60, and 90 degrees. Sketch sin(x) by hand and verify your calculations make sense.

TA office hour schedule

Kelly has scheduled her office hours for the entire semester. These are listed on an updated version of the class schedule in the syllabus available from T-Square. They are also listed below. All of Kelly's office hours will be in the computer lab from 2-3pm on the days listed below:

Th 5/17
T 5/22
Th 5/31
T 6/5
T 6/12
Th 6/21
Th 6/28
T 7/3
Th 7/12
T 7/17
T 7/24

Thursday MATLAB exercise

Access MATLAB’s help files another way by typing helpwin. Find out what the commands clock and date do.

No office hour on Thursday May 17

I will not be able to hold my office hour on Thursday because I am a committee member on a PhD oral exam that was scheduled some time ago. I will be available after class if anyone has questions to they want to discuss.
Prof. Sholl

Wednesday MATLAB exercise

Most days during the semester, I will post a short MATLAB exercise. These exercises are intended to take just a few minutes and to give you ways to broaden you experience with MATLAB.

Today's exercise: Use  MATLAB’s help files to understand how the format command works. Access the help files from the command window by typing help format. Alternatively, access the help files via the dropdown Help menu. Find the 12^th digit of the area of a circle with radius 2.64.

Reading for lecture 2

The reading assignment for lecture will be distributed in class today. Future reading assignments will only be announced via the blog.

Reading for Lecture 2: CC = Chapra and Canale

CC 9.2 Gauss Elimination (skip 9.2.1)

CC 9.3 Pitfalls of Gauss Elimination

CC 9.4.1, 9.4.2 Techniques for Improving Solutions

TA office hours survey

TA OFFICE HOURS SURVEY (open until Tuesday, May 22)
Students, please indicate your preferred meeting time for TA office hours using the survey below. Office hours will be held on Tuesdays, Wednesdays, or Thursdays depending on the class schedule. Often students use office hours to get assistance in completing assignments or to review exam content. Filling out the survey will increase your chances of selecting a time that works for you!
