Re: New publications
Hello Rajesh, thanks for pointing to some problems. However, it is still unclear, where you have found the error, because the link you mentioned is just a web site using frames. Could you please send us the URL on which the "error" occurred? You can find it by opening the frame in a separa...

Re: joint recurrence plot software
First, I forgot to mention that you can also use the "commandline recurrence plot" tool, which allows to calculate RQA from bivariate JRPs. However, for your purpose it could be more interesting to compare the diagonal-wise computed RR of the two data series, as it is performed to study ph...

Re: joint recurrence plot software
Can you use Matlab? Then you could use the CRP toolbox. Using this toolbox and with few lines of code you can compute RQA of JRPs. But may I ask why you need to compute the RQA measures from JRPs? What is your goal?

Re: 3rd RP Workshop - Locations
I would suggest to have it every two years. Thus your suggestion fits well.

Re: 3rd RP Workshop - Locations
Hi Raphael,
I love the idea to move the workshop to a more focused view, i.e. that the next workshops are more dedicated to special topics.
Thanks for your suggestion of Montreal. This would also be a great location.
I hope that we have also some further comments on that issue.
Best regards
Norbert

Re: Complex data
Dear Adrian,
you can try the command crp2, which allows to compute a recurrence plot from a multicolumn vector, representing the phase space vectors, or, as in your case, the two components real and imaginary part.
Best regards
Norbert

After visiting Angelo in the very beautiful Siena, I also suggest to organise the next RP workshop there. We intend that the meeting would be in September 2007. Note that it would be an anniversary, because of 20 years of JP Eckmann's paper in Europhysics Letters. We look forward to meet all of you ...

You could utilise joint recurrence plots (JRP), which are real multi-variate tools. Although in publications the JRPs are used as bi-variate tools, do not hesitate to apply them as multi-variate tools. Have also a look at the comments and suggested literature at http://forum.recurrence-plot.tk/viewt...

I could bge that the signals will be modelled in diferent embedding dimensions. I recon that it would be best to measure this first before continuing these speculative questions (:=))) but anyhow even if the embedding dimension for the model should differ could chose the one of the most direct sign...

How to find out which system leads the other by using CRPs
In order to find out which system drives the other, from the CRP you could compute a RQA measure defined diagonal-wise (i.e. not for the entire RP but only for the k th diagonal parallel to the LOI), e.g. RR( k ). The measure RR( k ) or RR( -k ) means the recurrence density in the diagonal above or ...

But what about the problem if both signals do not have the same embedding dimension ? Can You still use CRP ? This is exactly the problem. The purpose of CRPs is to compare the states of two processes, what means that the states represent the same physical process, i.e. the data should have the sam...
