For one of my projects at work I had to figure out a way to sort through a whole bunch of data and easily find something that was needed. Because we use MATLAB in school, I decided to use MATLAB to do what I needed. I began writing a whole bunch of lines of code and it turned out that the code was taking longer than I expected. The next day when I began to work on the code, I forgot what some of the lines of code did and what they were used for. Unfortunately, I had to restart because at that point it would have taken me longer to figure out what the line meant than to start over. Once I restarted, I began commenting the lines of code so that I can easily figure out what it did. Not only that, when I submitted the program to my boss, she also wanted to see how the code worked. With the comments she was easily able to figure out what was running and she could easily change whatever she needed to sort through the data.
