EEG non linear feature extraction on epochs or channels or segments problem

Hi everyone

I have some EEG signal which are loaded in MATLAB like segments*channels*epochs (e.g. 1000*19*57). Idk how should I extract complexity features like lempel-ziv. Idk how should I binerized my EEGs and using LZ function on epochs or channels or segments?

(I already had the lempel-ziv function)

many thanks in advance

Hi @Mehrnaz,

Here is a MATLAB resource for computing the Lempel-Ziv complexity using the “calc_lz_complexity”from the File Exchange on EEG signals:

Additionally, here is a link to the MATLAB File Exchange, which offers support for various types of EEG feature extraction:
