How to run MATLAB on Athena: To run MATLAB codes using computers in the Athena cluster (No dialup): Step 1. Log in to your Athena account. Then, open up a command prompt (terminal). Step 2. If this is your first time running MATLAB on Athena, at the command prompt, type (without the ">>", which I'm using to denote the command prompt): >> mkdir ~/matlab This creates a new folder called "matlab" under your home directory. Step 3. Type (again, if this is your first time running MATLAB on Athena): >> add matlab This enables matlab to be run under your user name. From this point on, you will skip steps 2 and 3. Step 4. To start MATLAB, type: >> matlab All the codes that you'll be running should already be in the newly created (in step 2) folder "matlab". So if you don't already have the downloaded codes there, transfer them over to your "matlab" folder. Once you've done that, in the matlab console, you have the followign options, depending on what you want to do: a. To run an already exisiting code, type: >> underdampedSHM % This will run a code called "underdampedSHM.m" >> criticallydampedSHM % This will run a code called "criticallydampedSHM.m" >> overdampedSHM % This will run a code called "overdampedSHM.m" b. To edit an already exisiting code, type: >> edit underdampedSHM.m % This will open up a "text editor" (MATLAB code editor) % that will let you start changing parameter values etc. ======================================== To run MATLAB codes on Athena using your own computer (dialup): Step 1. Open up "x11" on MAC, or a terminal (such as "xterm") on windows. Or, whatever software you use to SSH into outside networks. Step 2. At the command promp of x11 or your SSH client, type >> ssh -XC -c blowfish -l YOURUSERNAME athena.dialup.mit.edu where YOURUSERNAME is your user name on Athena. For example, I would type >> ssh -XC -c blowfish -l hyouk athena.dialup.mit.edu. Now, you are logged into Athena remotely from your computer. Go through steps 2, 3, and 4 of above and start running MATLAB codes.
