New functions in CRP Toolbox regarding corrections

Post by Norbert »

After long time some new functions (embed, skel_crp, dl) have been included into the Cross Recurrence Plot Toolbox for MATLAB, mainly providing the corrections proposed in Kraemer & Marwan, Phys. Lett. A 383 (2019). DOI:10.1016/j.physleta.2019.125977 .

skel_crp is a new function and allows to clean a recurrence plot from such recurrence points that are caused by sojourn points (and result in undesired thickening of diagonal lines in the RP). The crqa and dl functions are extended and now include the Censi and KELO correction schemes for border lines – important, e.g., for calculation of recurrence plot entropy of cyclical signals.

See the paper mentioned above for more information.
