MATLAB is used extensively in the laboratory exercises provided. This appendix provides an overview of MATLAB and some of its capabilities. We focus on programming issues since a wealth of information is already available on syntax and basic commands. MATLAB has an extensive online help system, helpdoc, which can be used to answer any questions not answered in this brief presentation. In fact, an ideal way to read this appendix would be to have MATLAB running so that help can be used whenever necessary, and the examples can be run and modified.
