Hi,
I currently have a program that uses the plot function to generate a graph. I would like to write the graph into a document. I am very new to matlab and coding in general, and so far have been unable to locate the relevant documentation.

These links have been really helpful, I also have been looking at the ones mentioned here about putting multiple pdfs into one document. https://www.mathworks.com/matlabcentral/answers/745882-multiple-plots-to-one-pdf
You may be able to clarify something,
When I plot something say plot(x, y) I get a figure (graph that I can view), but as far as I understand plot(x, y) is not an obj. Since an obj is any type of axes, figure, etc. Therefore something like
exportgraphics(plot(x, y), 'filenamehere.pdf');
is invalid (to my understanding).
If I had two columnar vectors (arrays) x and y and I wanted to use export graphics I would need to somehow turn them into an obj (a broad term). What type of function or command would I utilize to accomplish this?

plot() returns an array of "primitive chart line" objects. Surfaces, images, lines, patches, text, are the traditional low level objects; there are now a lot of additional low level objects built around a new layer of even lower level objects
