Hello everyone, how do you average the 10 largest data in u(m/s) in each .txt file in a file set? Then draw these data. Thank you very much.

fileList = dir('PIV*.txt');
for k = 1 : length(fileList)
    thisFileName = fullfile(fileList(k).folder, fileList(k).name);
    dataStructure = importdata(thisFileName)
    data = dataStructure.data;
    % Get u from column 3.
    u = data(:, 3);
    % Get 10 largest
    big10 = maxk(u, 10)
    % Get the mean
    mean10 = mean(big10)
end
