Re: Eckmann 1987 vs 1995
Norbert, this phenomenon is unfortunately quite common especially when citing textbooks or article collections. It might stem from laziness, it's easier to copy a citation from another publication.Note that the 1995 version provides some clarifications but is still largely based on the 1987 work. I...

Re: Eckmann 1987 vs 1995
This phenomenon is obviously caused by Google Scholar: https://scholar.google.de/scholar?q=%22Recurrence+Plots+of+Dynamical+Systems%22 . It does not show all versions of this reference, only the 1995 version. The complete list is available when clicking for "more results". https://scholar....

Eckmann 1987 vs 1995
Really strange situation: Since a few months I observe that many papers cite now the reprint Eckmann et al: Recurrence Plots of Dynamical Systems, In: Turbulence, Strange Attractors and Chaos, World Scientific, Singapore, 1995, https://doi.org/10.1142/9789812833709_0030 instead of the original work ...

11th Recurrence Plot Symposium in Mexico
The next symposium (in 2025) will be most likely in Mexico City.

Re: Multivariate non-time series
Similar to this previous question: (http://forum.recurrence-plot.tk/viewtopic.php?f=4&t=3591). I'd like to take multivariate data (independent feature1, feature2, ..., featureN) and convert each row into an image for classification. There are perhaps 10 features as well as a dependent variable,...

Re: 10th Recurrence Plot Symposium in Japan
We would like to announce the 10th International Symposium on Recurrence Plots which will be held at the National Institute of Advanced Industrial Science and Technology, Tsukuba, Japan, August 28-30, 2023; as a satellite conference of ICIAM 2023 in Tokyo. For the moment, we plan a regular conferenc...

Re: Transitivity?
Referring to Reference Manual Version 5.22, Release 32, are there any scientific papers defing or discussing "local recurrence rate" and RQA measure #13, Transitivity? There are not so many on the local RR (although I have included it in my lectures on recurrence analysis). The first one ...

Re: function for general synchronization
Dear sir, I wanted to ask if there exists any function in the CRP toolbox to compute GPR for general synchronization like there exists CPR for phase synchronization? No, because the calculation is so easy. You have simply to calculate the RPs of the individual systems and multiply them to get the J...

Re: Installation in HPC
Hi, I'm not sure about the architecture of your HPC. But in our system,we have a login node where I can install and test software. Then, when submitting the job, the used nodes are able to access the same folder. Thus, no problem. In your case, as far as I understand, you have no access to the used ...

Re: unthresholded recurrence plots images
Hi All, I want to use CRP for calculating RQA. R = crp (x) gives the threshold matrix. Is there any way to have the unthreshold matrix or save unthreshold RQA image? Regards Sure. As it is specified in the help of this function, the corresponding flag is "distance" (or in short "dis&...

New functions in CRP Toolbox regarding corrections
After long time some new functions (embed, skel_crp, dl) have been included into the Cross Recurrence Plot Toolbox for MATLAB , mainly providing the corrections proposed in Kraemer & Marwan, Phys. Lett. A 383 (2019). DOI:10.1016/j.physleta.2019.125977 . skel_crp is a new function and allows to c...

Re: pss function and other methods to find proper radius for CRQA
Yes, for radius I meant recurrence threshold ε. As for the research question i'm interested in analyzing the dynamics between two people performing the same movements at the same time. To this regard if I were interested to just the line of synchronization, inputting in the crqad function a lag = 0...

Re: RR calculation using CRQAD and phasesynchro
Should be the same. I have to check. Perhaps there is another norm selected or the time series was normalised by default. Do you have a short example? I could use it to check the code.
