jrpPurposeCreates a joint recurrence plot. Syntax
jrp(x,y) jrp(x,m,t,e) r=jrp(x,[],m,t,e) r=jrp(x,m,t,e,'param1','param2',...) r=jrp(x,y,m,'param1') DescriptionCreates a simple joint recurrence plot of maximal two data series, based on different norms or recurrence plots. Embedding parameters will be the same for both systems. Results can be stored into the workspace. Allows to change the parameters interactively by using a GUI. The source-data x and test-data y can be one- or a two-coloumn vectors (then, in the first column have to be the time); if the test-data y is not specified, a simple (auto) recurrence plot is created. ParametersDimension m, delay t and the size of neighbourhood e are the first three numbers after the data series; further parameters can be used to switch between various methods of finding the neighbours of the phasespace trajectory, to suppress the normalization of the data and to suppress the GUI (useful in order to use this programme by other programmes).
Parameters not needed to specify. LimitationsFor higher speed in output the whole matrix of the recurrence plot is in the work space - this limits the application of long data series. However, with a little Matlab script, long data series can be handled too (cf. Examples for crp). Examples
b=sin(.01*([1:1000]*2*pi/67).^2); jrp(a,b,3,12,'fan') See AlsoReferencesRomano, M., Thiel, M., Kurths, J., von Bloh, W.: Multivariate Recurrence Plots, Phys. Lett. A, 330, 2004. |
