A rather old but still usefull introduction for the starting user is the PRTools4.1 manual. Also the book “Classification, Parameter Estimation and State estimation” has many example scripts using PRTools. There is also an e-book “Pattern Recognition: Introduction and Terminology“, referring to on-line PRTools examples.

The authors originally maintained the website, 37Steps, with more recent information on the toolbox and pattern recognition. The most relevant pages are included in this website and can be accessed by Guide. Also the Glossary, the Frequently Asked Questions section, and the Blog are imported from 37Steps.

The toolbox itself contains several examples and example scripts. If you still have a question, please send a message.
