First of I am a newbie here. I have read "MARWAN, N., Romano, M. C., Thiel, M., Kurths, J.: Recurrence Plots for the Analysis of Complex Systems, Physics Reports, 438(5-6), 2007, 237-329". I would like to implement JRP in my synchronization problem.

While basic material, I was not able to understand "reconstruction of Phase space". Does it really required in order to compute JRP between two dynamical systems?

Also if a system has 4 co-ordinates then for synchronization problem do I get 4 JRP plots?

I am sorry that I was not able to understand those completely from the above paper.

Thank you in advance.
