"Sort function not working for me"

Did you download NATSORTFILES from here?:

https://www.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort

Did you unzip it onto the MATLAB Search Path? (e.g. into the current directory)

Do you get an error message? If so, what is the complete error message?

 F=sort("file"+(1:14)+".mat"); F=F(randperm(end))  %Unordered file list

F = 1x14 string array
  Columns 1 through 11

    "file2.mat"    "file10.mat"    "file12.mat"    "file1.mat"    "file9.mat"    "file14.mat"    "file8.mat"    "file13.mat"    "file6.mat"    "file11.mat"    "file5.mat"

  Columns 12 through 14

    "file3.mat"    "file7.mat"    "file4.mat"

[~,is]= sort( str2double(extract(F,digitsPattern)) );

F=F(is) %list of files sorted

F = 1x14 string array
  Columns 1 through 11

    "file1.mat"    "file2.mat"    "file3.mat"    "file4.mat"    "file5.mat"    "file6.mat"    "file7.mat"    "file8.mat"    "file9.mat"    "file10.mat"    "file11.mat"

  Columns 12 through 14

    "file12.mat"    "file13.mat"    "file14.mat"
