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.
You can use MATLAB for free once you create a MathWorks Account using your @ucsd.edu email address. Follow the steps in the link to create the MathWorks Account and install MATLAB. If you are using a Mac and your system is not up to date, older versions of MATLAB are sufficient for the MATLAB assignments. Click here to see how to install an older release.
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. 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 at 11:59pm on Monday, October 16 PT |
2. Visualizing Solutions to ODEs | Due at 11:59pm on Wednesday, October 25 PT | |
3. Numerical Methods | Due at 11:59pm on Wednesday, November 8 PT | |
4. Systems of ODEs | Due at 11:59pm on Wednesday, November 22 PT |
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 (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. Two random exercises will be graded each time.
MATLAB Tutoring
MATLAB tutors are available to provide help with MATLAB during Week 2-10; their scheduled hours are available in the upper left of this webpage. You may go to different tutors' tutoring hours via Zoom.
Please note that there are no regular MATLAB sections and the lab hours in webreg do not mean anything.
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 can 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 MATLAB final quiz will be held
0:00 am PT on Wednesday, December 6th until 11:59 pm PT on Thursday, December 7th |
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.
