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.
Due to the COVID-19 pandemic, the computer labs in AP&M are no longer available. You may install MATLAB on your own computer (not a Chromebook) for free following instructions here. We recommend this. More detailed information can be found at Working from Home on the sidebar.
If you don't have a computer, there is an option to request a loaner laptop here. MATLAB online works well if you use a Chromebook or you simply don't want to install MATLAB. You can use it for free once you create a MathWorks Account using your @ucsd.edu email address. If you don't have a computer but you have a tablet like an iPad, you can use MATLAB Mobile with a MathWorks Account. CloudLabs also works and instructions are here but it can be quite slow. Note that you need to connect via UCSD VPN to use CloudLabs.
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.
Assignments | 1. Introduction to MATLAB | Due at 1pm on April 16 PDT |
2. Systems of Linear Equations | Due at 1pm on April 30 PDT | |
3. Matrix Algebra | Due at 1pm on May 14 PDT | |
4. Eigenvalues & Diagonalization | Due at 1pm on May 28 PDT | |
5. Orthogonality & Least Squares | Optional (not covered in the quiz) |
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. Assignment 5 is not required for this class and it will not be covered in the final quiz. It offers you an opportunity to learn more.
Homework should be uploaded to Gradescope by 1:00 pm (San Diego time) 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. Four random exercises will be graded each time.
MATLAB Tutoring
MATLAB tutors are available to provide help with MATLAB during Week 2-9; their scheduled hours are available via the link in the sidebar. Please note that there are not any regular MATLAB sections. You may go to different tutors' tutoring hours via Zoom. Information about the meeting IDs will be provided on your Canvas page.
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 4.
- You may make use of gradescope and the course websites but no other websites.
- The quiz is scheduled for one hour, although you most likely will not need the full amount of time.
- Open book and notes. But you may not disclose the exam problems to any other person during the quiz days. Any sign of disclosure will be reported immediately to the Academic Integrity Office.
- The quiz will be offered in Quizzes on Canvas. The problems are in the forms of multiple choices, numerical answers, etc. You don't need to write/scan anything.
Quiz Time
The Math 18 quiz will be held
0:00 am PDT on Wednesday June 2 until 11:59 pm PDT on Thursday June 3 in Week 10 |
in "Quizzes" section on Canvas. |
You can take it whenever the time is convenient for you during the period. The quiz starts the first time you access the quiz and ends after 60 minutes.
We do not offer make-up quizzes if you miss your quiz.
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. Please include in the email your class information like the lecture code or your instructor. Also, note that the MATLAB TA only coordinates the MATLAB part. You should ask your regular TAs questions about regular lecture material.
