Thank you Roger. I appreciate your answer. I am very new to MATLAB and I clearly have no idea what I'm doing. Again, I really appreciate your help.

Emily Gobreski comments to John:

I'm sorry you feel this way. I have this huge project due using MATLAB software, and I'm a first time MATLAB user. I do not wish for anyone to do the project for me. I just have no clue what I am doing.
