crp2
Limitations
Normalization of the data series.
’normalize’ – Normalization of the data.
’nonormalize’ – No normalization of the data.
Suppressing the GUI.
’gui’ – Creates the GUI and the output plot.
’nogui’ – Suppresses the GUI and the output plot.
’silent’ – Suppresses all output.
Parameters not needed to be specified.
For 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,
a solution for using long data you can find under the description for crp.
Examples a=sin((1:1000)*2*pi/200); % pendulum’s location vector
b=cos((1:1000)*2*pi/200); % pendulum’s velocity vector
crp2(a(1:500),b(1:500),’nonorm’,’euclidean’)
b=sin(.01*([1:1000]*2*pi/67).^2);
crp2(b(1:500),a(1:700),3,10,.06,’fan’)
