For the computing portions of the assignments, it is not enough to print out pages of output and code without commentation and little discussion. Instead, to get a full credit, it is required to include two important things (1) a 1-2 paragraph summary of your results and (2) your results (including convergence and error results) in tabular format. This will allow you to gather your ideas for better performance.
It is your responsibility to present your Homework in a best possible way. Please write neatly (better type), and respect grader/instructor time. Do not expect grader/instructor to figure out what you meant. Make it crystal clear!
