MATLAB for Math 18
Welcome to the gateway page for the MATLAB portion of Math 18! This part of the course is an introduction to the use of computer software to solve problems in linear algebra. These kinds of computations are valuable tools not only in pure mathematics but also in physics, chemistry, biology, computer science, economics, and sociology.
All of these fields deal with vast amounts of raw data that may be difficult or impossible to work with by hand. Computer programs like MATLAB help by performing tedious calculations error-free, so that you can avoid wasting all your time crunching numbers. It turns out that MATLAB is especially well suited for working with matrices and performing various algorithmic routines that come up in linear algebra.
In general, each assignment in this course is self-contained and can be completed without prior MATLAB experience, although some assignments depend on commands learned in earlier ones. There are no limitations on when you may use the computer lab in AP&M B432 (B349 in the summer), and you can spend as much time as you wish on each assignment as long as you submit it on time.

Assignments | 1. Introduction to MATLAB | Due Aug 16 |
2. Systems of Linear Equations | Due Aug 23 | |
3. Matrix Algebra | Due Aug 30 | |
4. Eigenvalues & Diagonalization | Due Sep 6 | |
5. Orthogonality & Least Squares | Optional |
The due dates above are the standard dates for all Math 18 classes, but please note that your instructor may assign different dates, in which case his or her assigned dates take precedence. Please check your class's website to verify due dates.
Homework should be uploaded to Gradescope by 11:59 pm on the listed due dates. (See the instructions within Assignment 1 for more information.) Be careful to pace yourself with the rest of the course; if you see a midterm coming up near a MATLAB due date, it is to your advantage to do your homework early.
MATLAB Tutoring
In the summer, the TAs from your class will be in the MATLAB lab during the lab times listed on your course schedule. These will be the only times when tutoring is available, although you are free to work in the lab on your own at other times.
The MATLAB Quiz
During the last week of the quarter, you will have to take a MATLAB quiz.
- You will be tested on your ability to use rudimentary MATLAB commands to solve basic computational problems and on your understanding of topics covered in the lab assignments.
- The quiz will cover Assignments 1 through 5.
- The quiz is open book and open notes. You may even make use of the labs you've completed during the quarter.
- The quiz is scheduled for 50 minutes, although you most likely will not need the full amount of time.
- You need not bring anything to the quiz except a pen and a photo ID.
To help lighten the load on proctors, please do the following when you arrive for the quiz:
- Sit at an open terminal and put your photo ID on your desk.
- Once your proctor gives you your quiz, immediately fill in your name, your TA's name, and your instructor's name in ink.
- You may then start working immediately.
Quiz Times
Your quiz time is based on the discussion section in which you are officially enrolled. For Summer Session I, the Math 18 quiz will be held in APM B432 on Thursday, September 6, at the times listed below:
Section | Quiz Time |
A01 | 1 pm |
A02 | 2 pm |
A03 | 3 pm |
A04 | 4 pm |
If you are unable to make it to your assigned quiz time, you have the option to instead take an alternate quiz at a different time. During week 4, the week before the quiz, you will be able to go sections.ucsd.edu and select an alternative time. Sign-ups will open on Monday and will close at noon on Saturday of week 4. If you fail to sign up during this time, you will not be able to take the alternate quiz.
This summer, alternate quizzes will be offered on Wednesday, September 5, at 1 pm, 2 pm, and 3 pm.
We do not offer make-up quizzes if you miss your quiz.
If you have any questions about the MATLAB quiz or the alternate quiz times, please email the Senior MATLAB TA.
Feedback
If you have any suggestions or comments about the lab assignments, we'd love to hear from you. Also, if you encounter any mistakes or broken links, let us know. Send an email to the Senior MATLAB TA.
