| **Instructions:** Use the ''diary'' feature to create a diary file to record your Matlab session. Run ''format compact'' to save electrons and ultimately trees. Solve the problem set, then turn the diary off. Edit the diary with a text editor to remove mistakes, then print out the diary, write the names of your work group members on it, and turn it in. | **Instructions:** Use the ''diary'' feature to create a diary file to record your Matlab session.
