How to Hand in Matlab Homework for MATH 246

Read section 4.4 ``Presenting Your Results'' in "Differential Equations with Matlab". You will only receive credit for your homework if you follow the following rules:

• Printouts of interactive input at the Matlab prompt will not be accepted! You must prepare an m-file problemX.m containing the commands for each problem.
• All printed numerical values must be labeled, all graphics must be labeled
• Print out only those values which were asked for in the problem!
• Describe your observations and answer all questions asked in the problem.

The easiest way is to use the publish command (available in Matlab 7 or higher). Your m-file contains the main title (starting with %%), then a "cell title" (starting with %%) followed by comment lines (starting with %), followed by Matlab commands, followed by additional "cells" in the same format. The publish command then generates an html file (which you can print from a web browser) or a Microsoft Word file containing input, output, and graphics. See also sections 4.4.3 (p. 43) and 4.4.5 (p. 45) in "Differential Equations with Matlab").
Example: From the m-file publish_example.m we generate the web page publish_example.html with the command publish publish_example

If you don't use publish: For each problem hand in

1. a printout of the file problemX.m containing the Matlab commands, and comments answering the questions asked in the problem. Also include comments for each plot command indicating which of the attached graphics it produced.
2. a printout of the Matlab output.
3. a printout of all graphics. Clearly label all graphs and put a comment in the file problemX.m so that it is clear which Matlab command produced which graphic.
4. additional (possibly handwritten) pages containing answers to questions asked in the problem
