trackplot

Purpose

Estimates the line of synchronization of a cross recurrence plot.

Syntax

    trackplot(x)
    trackplot(x,dx,dy)
    trackplot(x,dx,dy,'param')
    a=trackplot(...)
    [a b]=trackplot(...)

Description

trackplot(x) estimates the line of synchronization (LOS) in a cross recurrence plot x. The resulted path is exported to the workspace variable t_out. This command allows the interactive changing of estimation parameters.

[a b]=trackplot(...) estimates the LOS and stores it in a. The number of recurrence points met by the LOS is stored in b(1) and the number of lacks in the LOS is stored in b(2).

Parameters

The search of the LOS can be forced with the parameters dx and dy. An additional flag param allows to suppress the GUI (useful in order to use this programme by other programmes).

Suppressing the GUI.
   'gui' Creates the GUI and the output plot.
   'nogui' - Suppresses the GUI and the output plot.
   'silent' - Suppresses all output.

Examples

    y=sin([1:900]*2*pi/67)';
    y2=sin(.01*([1:900]*2*pi/67).^2)';
    x=crp_big(y,y2,3,12,.1,'fan','nogui');
    trackplot(x,2,2)
