Hello, I have a signal of 30 minutes duration. It is a csv file. I want to divide it into non overlapping segments of 10 sec duration and save them as different recordings. The sampling frequency of the signal is 360 Hz. How can I achieve this in matlab?

Folder = 'E:\data_Lab\MITBIH\edited\';
X = xlsread('E:\data_Lab\MITBIH\edited\100.csv');
X1 = X(:,1);
t1 = 1;
t2 = 3600;
k = 1;
while t2 <= 651600
new_seg = X1(t1:min(t2,length(X1)));
File = sprintf('Part%04d.csv', k);
csvwrite(fullfile(Folder, File), new_seg);
t1 = t1 + 3600;
t2 = t2 + 3600;
k = k + 1;
end
