MATLAB gives me the splash screen, then just sits there...
 Go to a terminal window and type "ps u NETID" with your NET ID. There should be a process called "matlab". Get the number off it, then type "kill KILL NUMBER" (the adverb really is "KILL"). Then, go to your root directory, change into the .matlab directory and remove the contents with "rm ir *" (make SURE you are in the .matlab directory). Go back to where you were and start matlab again.

 Hit CTRLC to break out of Matlab.
How do you even get IN to MATLAB? I have no idea...
 After logging in to an OIT machine (or using MobaXterm to get there from a PC , or using X11R6 on a Mac to log in) just type
matlab &
at the command prompt.
How do you type MATLAB code in these pages, and how do you make it pretty?
 The SyntaxHighlighting extension is installed on this wiki, so all you have to do is use the appropriate source and lang tags. The code:
<source lang="matlab"> %% Postprocessing % take data from AI [data, time] = getdata(AI); %% plot data c1 = data(:,1); c2 = data(:,2); c3 = data(:,3); c4 = data(:,4); plot(time, c1, 'b', time, c2, 'g', time, c3, 'r.', time, c4, 'c:') legend('0', '1', '2', '3', 0) xlabel('Time (s)'); ylabel('Voltage (V)'); </source>
 produces
%% Postprocessing
% take data from AI
[data, time] = getdata(AI);
%% plot data
c1 = data(:,1); c2 = data(:,2); c3 = data(:,3); c4 = data(:,4);
plot(time, c1, 'b', time, c2, 'g', time, c3, 'r.', time, c4, 'c:')
legend('0', '1', '2', '3', 0)
xlabel('Time (s)'); ylabel('Voltage (V)');
 See the page linked above for other languages that are parsed.
How do I change colors and fonts?
In the File menu, pick Preferences and, in that window, look three different places:
 The Fonts section allows you to change fonts. Make sure to choose a monospaced font.
 The Colors section allows you to change most of the colors. Pay careful attention to the sample color block in this window to make sure you can read all the different colors of text.
 The Editor/Debugger section has a Display subsection  this is where you can control the color of the current line (the default is not to alter it) as well as the color of a highlighted section (i.e. a segment of code under a %% comment)
How do logical masks work?
 See the Logical Masks page in the MATLAB name space.
What do the line number mean on the CB68LP card?
 See the CB68LP_Pinout page in the MATLAB name space.
How can I use inline functions?
 See the Inline Function page in the MATLAB name space.
How can I use anonymous functions?
 See the Anonymous Function page in the MATLAB name space.
How do I define a function in a text file?
 See the Userdefined Function page in the MATLAB name space.
How do I run MATLAB without the GUI?
When attempting to use MATLAB on a Unix machine when you're not at Duke, it's often easier to refrain from opening the GUI (which can be too slow). Here are some steps around that.
 SSH into a Unix machine
 Navigate to directory with MATLAB Script
 Ensure MATLAB Script has the command 'exit' on its last line
 type 'which matlab' into the command prompt, which should output something like /usr/bin/matlab
 Assuming the output is /usr/bin/matlab, enter '/usr/bin/matlab nosplash nodisplay nodesktop < fileToRun.m > outputFile.txt' into command prompt
 Open outputFile.txt by typing 'cat outputFile.txt' into the command prompt. This will allow you to see the text output of the MATLAB file.
Note: If you want to view images, type the "print dpng 'figureToView.png';" command after each plot in your MATLAB script. A .png file will be saved in the same directory after compilation.
