unthresholded recurrence plots images

Post by mehdi.bejani »

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"):

Code: Select all

D = crp(sin(0:.01:23), 'dis');
imagesc(D)
