We'll cover other helpful plot functions to enhance your plots.

More examples of plotting. 

After this lecture you'll be able to load and save data files. 

Examples of loading and saving data files.  You will need the downloadable data files found at the beginning of this section. 

Download test_data.txt to your working MATLAB directory and then test out your knowledge on quiz 7. My solution is given.

After this video you'll be able to create your own user-defined functions.
