The toolbox contains MATLAB^® routines for computing recurrence plots and related problems. New developments as extended recurrence quantification (Marwan et al., Phys. Rev. E, 2002), cross recurrence plots (Marwan & Kurths, Phys. Lett. A, 2002; Marwan et al., Nonlin. Proc. Geophys., 2002) and joint recurrence plots (Romano et al., Phys. Lett. A, 2004) are included.

Note: A prototype for estimation of confidence intervals for RQA measures is available at http://www.agnld.uni-potsdam.de/~schinkel/rqaci.php. We plan to include it in the CRP toolbox in the near future.

The most programmes contain a user-friendly graphical user interface, a pure command-line application of the programmes is also possible.

This toolbox requires Matlab 7 or higher.

Parameters in [ ] are optional.

Thanks

The development of is toolbox was partly supported by the projects Nonlinear Phase and Correlation Analysis of Palaeomagnetic and Palaeoclimatic Records within the Priority Programme SP1097 Geomagnetic variations: Spatio-temporal variations, processes and impacts on the system Earth of the German Science Foundation (Deutsche Forschungsgemeinschaft), the project BONE3D (MAP AO-2004-125) of the Microgravity Application Program/ Biotechnology from the Human Spaceflight Program of the European Space Agency, and the BioSim Network of Excellence.

Moreover, I'm especially grateful to Giovanna Varni (Genova, Italy), Paolo Sirabella (Roma, Italy), Shine Lu (Nan Jing, China), Charles L. Webber (Chicago, USA), Joseph P. Zbilut (Chicago, USA), Simon Mandelj (Slovenia), Denis Mottet (Montpellier, France), and Eleni Vlahogianni (Athens, Greece) who sending me error reports and hints for further improvement of the toolbox.

Remarks

This toolbox needs Matlab 5.3 or newer because it uses commands that are not available in previous versions.

The toolbox is still under development. We cannot give any warranty for anything related with our programmes. Please send error messages or comments to our contact address.

Future releases

We plan to improve and accelerate the toolbox routines and to include further methods of nonlinear data analysis.

A plain commandline version for creation of recurrence plots and RQA analysis is available for some Unix/Linux and Dos/Windows systems.
