Concatenated Segmentation using Overlapping Windows

I have a N-dimensional timeseries data with m samples (Nxm). I would like to sample the table with a fixed sized window of 50 samples with a shift of 5 samples, concatanating each sample in another table. What is an efficient algorithm to run this process?

hello
example below :
% dummy data
data = rand(80,5);
shift = 5; % nb of samples for averaging
buffer = 50; % nb of samples for averaging
for ci=1:fix((length(data)-buffer)/shift +1)
start_index = 1+(ci-1)*shift;
stop_index = min(start_index+ buffer,length(data));
out_data{ci} =data(start_index:stop_index,:); %
figure(ci),
plot(out_data{ci});
end
