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://people.physik.hu-berlin.de/~schinkel/rqaci.html. We plan to include it in the CRP toolbox in a future version.
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 newer.
Parameters in [ ] are optional.

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 (DFG), 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), Micahel Wess (Vienna, Austria), Eleni Vlahogianni (Athens, Greece), George Tzagkarakis (Paris, France), Arian Taghvamanesh (Tehran, Iran), Vahndi Minah (London, UK), Florian Ruch (Munich, Germany), Mircea Stoica (Hamburg Eppendorf, Germany), and many more who have sent me error reports and hints for further improvement of the toolbox.
This toolbox needs MATLAB 7 (MATLAB 2007) or newer because it uses commands that are not available in previous versions. It is working with MATLAB 2014b, but we recommend to use a MATLAB version before this release because MATLAB 2014b is significantly slower than previous MATLAB 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.
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.
