I want to spit EEG signals in four equal parts?

The matrix size is 65X1600

Kindly help me out to split it into 65x400 65x400 65x400 65x400

Thanks

If your EEG data is in the (65 x 1600) matrix named signal do:

 p1 = signal(:,1:400);
 p2 = signal(:,401:800);
 p3 = signal(:,801:1200);
 p4 = signal(:,1201:1600);
