EXTRA OFFICE HOURS FOR THE FINAL
Thursday, December 6, 3-5 pm, LSK 300B
Monday, December 10, 3-5 pm, LSK 300B
Lectures: Mon, Wed, Fri 1pm-2pm at room 182, Irving K Barber Learning Centre.
Course webpage: http://www.math.ubc.ca/~hajeong/Math307_2018W1.html
Text book: We will use the following online book as the main text.
Chapter 1 : Linear Equations
Chapter 2 : Subspaces, Bases, and Dimension
Chapter 3 : Orthogonality
Chapter 4 : Eigenvalues and Eigenvectors
Instructor: Halyun Jeong
Office hour: Thursday 3-5 pm, LSK 300B
Our goal is to cover most of the following topics in the course lecture notes: Interpolation, Finite difference approximations, Formula matrix of a chemical system, Graphs and Networks, Least squres, Fourier series, Fast Fourier Transform, JPEC compression, Power method, Recursion relations, The Anderson tight binding model, Markov chains, Google PageRank.
The course mark will be deteremined based on homeworks(10%), quizzes(10%), a midterm(30%), and a final(50%).
There will be weekly homework assianments. Please hand in your homework when the class starts on due date. The late homework will not be accepted but the lowest marked homework will be dropped in the final grade calculation. Students are encouraged to discuss homework, but should write up their homeworks individually.
Under any circumtances, there will be no make-up midterm. If a student misses the midterm with a valid reason, his or her final exam will be re-weighted to incorporate the midterm weight. The valid excuses for missing homework or exams include a prior approval of the instructor or medical emergency which must be supported by a physician's note within 72 hours. Missed homework, quizzes, exams without these reasons will be marked as 0.
All exams are closed books and no calculators are allowed.
There will be four in-class quizzes on Sep 19, Oct 3, Nov 7, and Nov 23.
The in-class midterm will be held on Friday, Octorber 19.
The final exam date is fixed by UBC (the date/time will be announced soon). Please plan your end-of-term travel carefully according to this date.
You can also access MATLAB in the math department computer lab which is located in LSK 310. The lab hours are posted here. You may use any free terminal in the labs during these times. Your username and password will be given out in the class. Let me know if you have difficulty in login. You may also use GNU Octave and they are also free. However, the instructor will only be able to answer questions regarding MATLAB.

Matlab files for problem 3,4 in problem set 1.2 splinemat2.m , plotcubic2.m , plotspline2.m
You need to save all these Matlab files in the same working directory or folder which is usually Documents/MATLAB.
Also beware that the function name and its file name should match (such as splinemat2.m, plotcubic2.m, plotspline2.m).
If this is still not working, type "path" command in Matlab command window and save matlab files in one of those working directories.
