% This function get an EEG measurement, devide it to epoches of 1 seconds
% with an overlap of o .5 second.  than organize it in the columns of a
% matrix S.
function [S]=data_matrix (a)

% a=1:1:1280;
N=length (a);
M=N.*2./128;
n=1;

j=1;
for i=1:1:M-1
S (1:1:128,j)=a (n:1:127+n);
n=n+64; % in order to get overlap of 0.5-s
j=j+1;
