Some software, scripts and toolboxes are available and may find your interest:
CRP Toolbox for MATLAB® allows for the creation of RPs as well as CRPs, quantification analysis of RPs and CRPs includes the new measures of complexity as LAM and TT, time scale alignment tool based on CRPs and further useful tools and methods of nonlinear time series analysis and data preparation are provided; platform independent (for MATLAB); both usage of graphical user interface as well as commandline call is possible
Commandline Recurrence Plots allows for the creation of RPs and their quantification analysis for really long data series; commandline based; currently for Unix/ Linux and Dos/ Windows
COPRA – Constructing Proxy Records From Age Models for MATLAB® is a depth-age modeling program that creates chronologies with uncertainties and can transform age-uncertainties to proxy-uncertainties.
Makeinstall tool for MATLAB®
creates a single, executable install file from comprehensive MATLAB toolboxes;
allows a user friendly installation of toolboxes, and simplifies their
The Makeinstall tool was selected on Oct. 3, 2014, as the Mathworks File Exchange Pick of the Week!
