PRTools

PRTools is the software package used in the book:

Classification, parameter estimation and state estimation - an engineering approach using Matlab

by Ferdi van der Heijden, Robert P.W. Duin, Dick de Ridder and David M.J. Tax, John Wiley & Sons, 424 pages, ISBN 0470090138, 2004.

The PRTools version used in the book is PRTools 4 (download ).  The recent version can be found here.

Code and data

The listings in the book can be downloaded as a ZIP archive, by following this link:

The data used in these listings can be downloaded as three separate ZIP archives:

The latter two files are distributed separately due to their size. The license plates data is needed only to run Listing 6.3; the time-of-flight data only for Listing 9.8.

Installation of the listings and the accompanying data is simple. Unpack (using, for example, WinZIP) the archives in a single directory, for example C:\CPESE. Start up Matlab and type:

>> addpath('C:\CPESE');

replacing C:\CPESE by the directory name you chose.

You can add this path permanently by editing your startup.m script. On Windows, this is stored in a subdirectory work of the directory you installed Matlab in. On Unix, it is usually stored in $HOME/matlab.

Projects

Three different projects have been defined, covering most of the topics in the book.
