Plotting X vs. Y

One way to plot one variable versus another is with the Plot() function of Matlab. Begin by opening up Matlab on the desktop, and entering the data in as vectors. Note that Matlab plots in the order that the points are given, so be careful that each value in the \(x\) and \(y\) vector corresponds with the next point. 

x=[1 2 3 4 5]; 
y=[1 4 9 16 25];
plot(x,y);

Of course, it would be useful to title the plots. This can be done in Matlab with the following lines: 

title('Y AXIS VS X AXIS')
xlabel('X AXIS LABEL') 
ylabel('Y AXIS LABEL')

Note that you can do \(\LaTeX\) Style subscripts using underscores in Plot Titles. Once you're done naming the plots, save them by clicking "file" and then "save as". Make sure to save as a JPG. Example plot:
