SEP 5 Lecture notes from today's class are posted below.
SEP 6 Homework 1 (due on Tue, Sep 17 in class) is posted below.
SEP 12   First office hour today at 11am in AUDX 142; Lecture notes posted below.
SEP 16   Quiz 1 will cover everything until the end of our coverege of condition number (all of I.1 in the typed lecture notes).
SEP 16   Here are some old midterm exams for additional practice. The following problems in these old midterms are on material covered in Quiz 1:

SEP 23 The lecture notes from Thursday Sep 19 are posted below.
SEP 23 The solutions to Quiz 1 are posted below.
SEP 23 Homework 2 (due on Tue, Oct 1 in class) is posted below.
SEP 25 The following files are for section I.2.6 from the lecture notes (which we will cover tomorrow). You will need plotspline2.m for Problems 3 and 4 in Homework 2, problems_1.2.pdf. Note that plotspline2.m needs the other two files below (splinemat2.m and plotcubic2.m) to be in the same folder as plotspline2.m. So, save these three files in the same folder and make sure your MATLAB command window is working in that folder.
splinemat2.m splinemat2(X) returns the spline matrix for the points X=[x1,...,xn].
plotcubic2.m plotcubic2(x_l,x_u,y_l,y_u,z_l,z_u) plots the cubic polynomial p(x)on the interval [xl,xu] with values p(x_l)=y_l, p(x_u)=y_u, p"(x_l) = z_l, p"(x_u) = z_u.
plotspline2.m plots the cubic spline through points X,Y when you type plotspline2(X,Y).
SEP 27 Quiz 2 will cover everything we did on interpolation (I.2.1, I.2.2, I.2.6, I.2.7). The following problems in the old midterms are on material covered in Quiz 2:
Midterm from 2016 WT1 : All parts of 4.

| COURSE INFORMATION
Class times and location:
Course web page for Section 103: http://www.math.ubc.ca/~erobeva/courses/WinterTerm1_2019/m307_103.html will be updated throughout the term.
This course is organized around a collection of interesting applications. Examples from past years are:
InterpolationWe will study a selection of these in this class. Each application will be preceded by discussion of the relevant concepts from Linear Algebra. These will be partly review from your previous linear algebra course and partly new material. You will also learn how to do Linear Algebra on a computer using MATLAB or Octave.
Learning Goals: See here for a detailed list of prerequisites and learning goals of Math 307.
Text: There is no required textbook for this course. Instead there is a set of typed notes designed for this course, which is available here:
Chapter 1 : Linear EquationsComputational aspects: To complete the work for this course, you will need access to MATLAB software. MATLAB is a widely used program for numerical computations with matrices. Since September 2016, MATLAB is available to all active UBC students at no cost. For instructions on how to download and activate MATLAB, see:
You can also access MATLAB in the math department computer labs. These are located in LSK 310. The labs 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 class. Please contact me if you have difficulty logging in. If you prefer, you may also use GNU Octave instead of MATLAB, which is an open source MATLAB clone that is available for free. It is included in most Linux distributions. Windows and Mac versions are available for free download. However, the professor will only be able to answer questions regarding MATLAB.
Homework: There will be weekly written homework assignments. These assignments will be posted below.
Quizzes: There will be 4 quizzes over the term: Sep 19, Oct 3, Nov 7, and Nov 21.
Late homework will not be
accepted. However, your lowest (written) homework
score will be dropped (so you can miss one homework if
necessary). Nevertheless, even if you miss a
deadline, its a good idea to do the problems, since this
is the best way to prepare for the tests and exam. You
are welcome to discuss the homework problems with your
friends, but you are expected to hand in your own work.
You will not be permitted to bring
calculators to the test and exam.
Your grade for the course will
be computed roughly as follows:
Missing a homework, quiz, or midterm:
If you miss
an assesment (homework, quiz, or midterm)
for a valid reason -- see UBC Vancouver Senate's Academic
Concession Policy V-135,
please fill out an academic
request form and bring it
to me. In this case, for a missed homework,
the weight will be transferred onto the
remaining homework assignment. For a missed
quiz, the weight will be transferred to the
remaining quizzes, If you miss the midterm,
the weight will be transferred onto the
Note that in accordance with UBC
policy for academic concessions, this form
may be used ONCE per course. On a second
instance, students will be expected to
who misses an assessment is to present to
their instructor a self-declaration form (or
relevant documentation if this is not the
first time they miss an assessment) within
72 hours of the assessment date or their
mark in the missed assesment will be 0. This
policy conforms with the UBC Vancouver
Concession Policy V-135 and students
are advised to read this policy carefully.
You will need a UBC email address to sign up for Piazza.
If you need help, or would like to
discuss any aspect of this course, please make an
appointment to see me in my office.
