I'm looking to plot a rectangular pulse and triangula

I'm looking to plot a unit step function from -2 to 2 and in between there is a unit ramp that goes from -2 to 1 and back to 2. I cannot figure out how to call the functions or plot them. I am just learning the program.

Have you looked at stairs function? For discrete data, stem function could be a choice too.

X = [0,1,2,3,4,5];
Y = [-2,1,2,-2,2];
stairs(X,Y)
ylim([-3,3])

For details and more examples, please execute

>> doc stairs

at your command window to see the documentation page.

I was trying to use the rectangular pulse and triangular pulse equation though.

Hmm, I must apologize that now I do see what you are trying to achieve here.

If you use Symbolic Math Toolbox, there's a function for rectangular/triangular pulse,

Once you define a function, fplot can be of help in plotting. See the examples in the above URL.
