obtain a copy of the Adobe Acrobat Reader for
free from http://www.adobe.com
. It should work in version 3.0 or later, but it works best with version 4.
Special instructions are noted on each assignment.
In general, Lab reports are due one week after doing the supervised warm-up.
Lab reports are due at the beginning of lab;
Labs turned in later on the same day will lose 5 points.
Please get the ZIP file of the SP-First M-files
Un-zip and put these files at the BEGINNING of your MATLAB path.
