computer symbol This designates that files

with MATLAB and MATHCAD computer

solutions are available However, within the

Solutions Manual itself, a MATHCAD

printed solution is shown (MATHCAD

solutions are shown since they clearly display

the algorithms used and the output takes up

less space.)

MATHCAD files and MATLAB M files for

these problems can be downloaded from the

Internet Web Sites maintained by the author.

These websites are located at
