MATLAB: Sorting one field of struct

sorting one field of struct

files=dir('*.dat');

i want to sort files.name of the files struct by file name

[junk, idx] = sort({files.name});
sortedfiles = files(idx);

Replace

[sorted_names,sorted_index] = sortrows({dir_struct.name}');

by the simpler:

sorted_names = sort({dir_struct.name});

Now you want to exlucde names, which contain the substring 'exclude'?

sorted_names(contains(sorted_names, 'exclude')) = [];

Or include files, whose name contains 'include':

sorted_names = sorted_names(contains(sorted_names, 'include'));

With older Matlab versions before contains was available, use:

function T = myContains(Str, Key)
T = ~cellfun('isempty', strfind(Str, Key));
end

images=dir('file*.tif');
n = {images.name}';
[~,ii] = sort(str2double(regexp(n,'(?<=file)\d*(?=\.txt)','match','once')));
images = images(ii);
