Here are some instructions for how to set your path in Matlab to link to these files.
Put the all files into a single directory:
Within matlab use addpath c:\matlab\lpbook
Note that this command could be added into a
startup.m file if you have one that gets
executed every time you start up matlab.
On Unix machines you could use a directory
called "matlab" in your home directory and
simply use the command "addpath /home/ferris/matlab"
