Getting Started

When can I access the MATLAB lab?
APM B432 and APM B349 remain unlocked from 7 am to 10 pm from Sunday to Thursday; they are open from 7 am to 5 pm on Friday and Saturday. On weekends, the doors to AP&M are locked, but you can open them by inserting your student ID into the card reader near the doors on either the north or the south side of the building and then pressing the automatic door button.

How do I log in to an ETS computer?
The ETS computers in the MATLAB lab require your usual ETS account username and password. Your username is the first part of your UCSD email address (before the
@ucsd.edu
). Your password is the same as your email password. If you can't remember it, visit this page. Extension students will need to sign up for an account here. 
How do I run MATLAB and Microsoft Word?
Open the Start menu at the bottomleft corner of the screen and begin typing either "matlab" or "word" to begin a search for these programs. To open MATLAB, choose the result that begins with "MATLAB r20___"; do not use the "Activate" or "Deactivate" programs.

Can I use a word processor other than Microsoft Word?
Yes. Any word processor will do the trick as long as it can handle graphics. (In other words, a simple text editor like Notepad won't suffice.)

Why can't I copy my graph into my Word document?
The problem is most likely that you're using Copy instead of Copy Figure from MATLAB's Edit menu.

Where should I save my files?
When working in the oncampus labs, feel free to use your home directory ("My Documents" in Windows). These files will be automatically copied to a separate file server when you log out, so that you can access them from any other ETS computer. You can also use online storage, like Dropbox, or removable storage, such as flash drives.

How do I print?
See the end of Lab 1 for instructions.

Am I supposed to print in color? Some of the graphs from MATLAB use colors.
No. Black and white is fine.

Working from Home

Can I do the labs from home?
You can. Instructions for obtaining a student MATLAB license for free from the university in order to install the software on your own computer (not a Chromebook) are available here. This is the preferred option.
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.
Alternatively, you could take advantage of UCSD's CloudLabs: HorizonView Service. Beware it can be slow. If you follow the instructions on the VCL page, you will be able to access MATLAB on your own computer as long as you're connected to a secured UCSD network (such as UCSDPROTECTED or RESNETCollegeE wireless). If you wish to access the software from off campus, you will need to first connect via a VPN.
For Math 20D, starting in the second assignment, you will need to download four Mfiles from this link. Once you've downloaded this folder, move each of the four MFiles into your working directory, which can be viewed at your current folder. If you can see those files in your current folder, then it's safe to use them. If you choose to use MATLAB online or MATLAB Mobile, you may upload those four Mfiles to your MATLAB Drive.

I'm using MATLAB on my home computer, and my results don't match what the lab says I should be getting. What's wrong?
By far the most likely explanation is that you simply made a mistake. If you're using your own MATLAB license, it's also possible that your version of MATLAB doesn't match the one installed in the ETS labs. Unfortunately, the TAs, tutors, and instructors cannot offer assistance on any computers except those in the the designated MATLAB labs. You use any other computer at your own risk.
Getting Help

Whom should I ask if I need MATLAB help?
If you've looked through MATLAB's
help
browser and have scanned this FAQ but you still have not gotten your question answered, ask a MATLAB tutor. If the tutor is busy helping someone else, you can also ask a neighbor. If you're working when tutors are not around, see the next question. 
What if I need help and there are no tutors in the MATLAB lab?
Firstly, do not email your lab to your TA to ask for help unless you've gotten their approval beforehand. The best way to get help is to work in the MATLAB lab when tutors are scheduled to be there, since some procedures are too difficult to describe in text alone. You might find that other students in the lab can help you out as well. If you're in the lab and a tutor is not present when he or she is supposed to be, please report the situation to the Senior MATLAB TA.

Whom should I talk to if I'm having trouble with the ETS computers?
Please point out the problem to a tutor if one is around; he or she might know a quick solution. If there is a hardware issue (for example, a keyboard or monitor seems broken), there should be a stack of ETS Problem Report sheets in the lab somewhere; please fill one out and place it on the computer.
