Hello. I am complete tyro in MATLAB. Just know few basics such as importing audio signals, image. Curently I am going to start a undergraduate thesis on EEG. I am having hard time asking myself the question how do I get the EEG data to import in MATLAB? I downloaded a sample file from Mathworks but I can't really grasp the first line of the code at the moment. I would be grateful if you could help. Here is the first few lines of the code that I downloaded.

load eegdata.mat;
s=eegdata;
figure;p=plot(s); 
title('EEG Signal')

Did you try the documentation?! Understanding what those 4 liines of code do should require nothing beyond reading

doc load
doc figure;
doc plot
doc title

and you can ignore figure and title really as being completely trivial!

Hello. Thanks I understand it now. Its EEGLAB. I was just woundering how we get the data at the first place. Now I just made a random data and found the signals. Thanks :)

If you can't find any public collection of signals online, then I'd head over to your university's medical school and ask around. See if a sympathetic neurologist over there can get you some, though patient privacy rules/laws may make them hard to get.
