hello
see example below :
samples = 40000;
buffer = 2000;
data = rand(samples,1)+10*((1:samples)/samples)'; % noisy ramp signal (dummy data)
for ci = 1:fix(samples/buffer)
start_index = 1+(ci-1)*buffer;
stop_index = min(start_index+ buffer-1,samples);
data_buffer = data(start_index:stop_index)
figure(ci)
plot(data_buffer)
end
