to sort the elements of a string/cell array use natsort:
to sort the rows of a string/cell array use natsortrows:
summary
alphanumeric sort the text in a string/cell/structure array. sorts the text by character code taking into account the values of any number substrings. compare for example:
>> a = {'a2.txt', 'a10.txt', 'a1.txt'};
>> sort(a)
ans = 'a1.txt''a10.txt''a2.txt'
>> natsortfiles(a)
ans = 'a1.txt''a2.txt''a10.txt'
by default natsortfiles interprets all consecutive digits as integer numbers, the number substring recognition can be specified using a regular expression: see natsort for details.
natsortfiles does not perform a naive natural-order sort, but sorts the filenames and file extensions separately to ensure a dictionary sort, where shorter filenames always sort before longer ones. likewise filepaths are split at each file-separator character, and each level of the file hierarchy is sorted separately.
example with dir()
p = 'c:\somedir\subdir';
s = dir(fullfile(p,'*.txt'));
s = natsortfiles(s);
for k = 1:numel(s)
f = fullfile(p,s(k).name)
end
file dependency
the natural-order sort is provided by the function natsort (file exchange 34464). all of natsort's optional inputs are supported by natsortfiles.
examples
>> a = {'a2.txt', 'a10.txt', 'a1.txt'}
>> sort(a)
ans = 'a1.txt''a10.txt''a2.txt'
>> natsortfiles(a)
ans = 'a1.txt''a2.txt''a10.txt'
>> b = {'test2.m'; 'test10-old.m'; 'test.m'; 'test10.m'; 'test1.m'};
>> sort(b) % wrong number order:
ans =
'test.m'
'test1.m'
'test10-old.m'
'test10.m'
'test2.m'
>> natsortfiles(b) % shorter names before longer:
ans =
'test.m'
'test1.m'
'test2.m'
'test10.m'
'test10-old.m'
%% directory names:
>> c = {'a2-old\test.m';'a10\test.m';'a2\test.m';'a1\test.m';'a1-archive.zip'};
>> sort(c) % wrong number order, and '-' sorts before '\':
ans =
'a1-archive.zip'
'a10\test.m'
'a1\test.m'
'a2-old\test.m'
'a2\test.m'
>> natsortfiles(c) % shorter names before longer:
ans =
'a1\test.m'
'a1-archive.zip'
'a2\test.m'
'a2-old\test.m'
'a10\test.m'
>> d = {'a1\b', 'a /b', 'a/b1', 'a=/b', 'a\b0'};
>> sort(d)
ans = 'a /b''a/b1''a1\b''a=/b''a\b0'
>> natsortfiles(d)
ans = 'a\b0''a/b1''a1\b''a /b''a=/b'
>> f = {'test_new.m'; 'test-old.m'; 'test.m'};
>> sort(f) % note '-' sorts before '.':
ans =
'test-old.m'
'test.m'
'test_new.m'
>> natsortfiles(f) % shorter names before longer:
ans =
'test.m'
'test-old.m'
'test_new.m'
