I have table.txt files in the subfolders of a directory. First I want to find the maximum value of a particular coulmn of the table.txt file. Then, I want to read these files in an ascening order based on these values. I can read the files. But unable to sort the files in the way I want to process the data further. Can somebody help me out?

allTables = dir('**/table.txt');

tablemax =zeros();

for ii = 1:numel(allTables)

thisFolder = allTables(ii).folder;

inFile = fullfile(thisFolder, allTables(ii).name);

A = readmatrix(inFile);

% do stuff ...

I=max(A(:,13));

tablemax(1:length(I),ii)=I;

end

iinew=sort(tablemax);

在 MATLAB Online 中打开

S = dir('**/table.txt');
for k = 1:numel(S)
    F = fullfile(S(k).folder, S(k).name);
    A = readmatrix(F);
    % do stuff ...
    I = max(A(:,13));
    S(k).max = I;
end
[~,X] = sort([S.max]);
S = S(X)
