Course Information:
If you haven’t already done so, please send me an email so that I can collect all of your email addresses for efficient communication of course information.
Please be sure to write your name and Lab number on your lab reports.
Please write a brief description of all results from the lab questions and include a labeled plot of your results and a copy of the Matlab code that you used (if it is a new or modified code). The easiest way to create an effective lab report is to create an MS Word document and copy and paste Matlab codes and figures into it.
