How to install

  1. Start MATLAB and change into the folder, where the downloaded files are located.
  2. Call the command install from the MATLAB command line; the toolbox will be automatically added to the startup.m file.

How to deinstall

Just call the command crpclean from the MATLAB command line. This will remove all files of the CRP toolbox from the filesystem and its entry from the MATLAB startup file.

If you encounter problems

First, please consult the FAQ. If you cannot find a solution there, you should use the Recurrence Plot Forum to ask for a solution. Please understand that we cannot answer every eMail regarding the CRP toolbox.

About the installation software:

The installation script was automatically generated with the MATLAB programme MAKEINSTALL. MAKEINSTALL might be of your interest, because it is easy to use and will safe time. It creates one distribution file from a bundle of MATLAB files.

This tool is free software and can be downloaded from the project site or from MATLAB Central.
