MATLAB for Math 20D


Welcome to the gateway page for the MATLAB portion of Math 20D! This part of the course is an introduction to the use of computer software to solve ordinary differential equations. The labs are meant not only to teach you how to use the software but also to help you see how the underlying algorithms actually work. The material also aims to give additional perspective to topics covered in the lecture, and it presents a few real-world applications that you might end up encountering in your major.

Due to the COVID-19 pandemic, the computer labs in AP&M are no longer available. You may install MATLAB on your own computer 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. For the options above, you need to manage some M-files starting in the second assignment. CloudLabs also works and instructions are here. Beware it can be quite slow but you don't need to manage those M-files. Note that you need to connect via UCSD VPN to use CloudLabs.

In general, each lab is self-contained and can be completed without prior MATLAB experience, although some assignments depend on commands learned in earlier labs.

Assignments 1. Introduction to MATLAB Due July 6
2. Visualizing Solutions to ODEs Due July 10
3. Numerical Methods Due July 17
4. Systems of ODEs Due July 24

The due dates above are the standard dates for all 20D courses, 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 summer, there are no undergraduate MATLAB tutors. You can find help from your TAs on the MATLAB problems.

The MATLAB Quiz

During the last week of the summer session, you will have to take a MATLAB quiz.

Quiz Time

The Math 20D quiz will be held

0:00 am PST on Thursday July 30 until 11:59 pm PST on Friday July 31
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.
