I am trying to evalute my Lab data, what are represtned into TXT files then plot the conntents of data.

      dataDirectory = 'files location  ';
      allFilesDir = dir(fullfile(dataDirectory , '*.txt'));
      allFN = {allFilesDir.name};
      result = [];
      for n = 1:length(allFN)
      measNr(n) = str2double(regexprep(allFN{n},'**.txt',''));
      myFN = (fullfile(dataDirectory, allFN{n}));
      auxv =try1(myFN);
      result(n,:) = mean(auxv.data);
      end

This code is workin but into wrong order arrangemnt the TXT files (0,1,11,12,13,14 .....) which give me wrong plot data. I used

plot(measNr,resultMG(1:35,2),'x');

but i read that i can use sort_nat in this way but it did not work for me .

       % [~, order] = sort_nat({result});
       % result = result(order);

and I got this error messge

       :??? Undefined function or method 'sort_nat' for input arguments of type
       'cell'.:

A simple solution is to use my FEX submission natsortfiles

http://de.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort

It sorts according to any numeric values in the strings, and also sorts the file extensions separately:

>> S = dir('*.txt');
>> S.name
ans =
    '1.txt'
ans =
    '10.txt'
ans =
    '2.txt'
>> S = natsortfiles(S); % alphanumeric sort by filename
>> S.name
ans =
    '1.txt'
ans =
    '2.txt'
ans =
    '10.txt'
