good morning I have a problem with the command "dir":
I want to find some files which names are f.e. : 10.txt,11.txt,12.txt, etc. and list them within a cell or an array
I tried with this:
for i=10:20
file = dir(fullfile(open_folder, ['*' i '*' '.txt']))
end
neither
file(i) = dir(fullfile(open_folder, ['*' i '*' '.txt']))
works (mismatched dimension or something similar).
the resulting structure is just the file with the last numerical value (i.e. '20.txt' in this case)
is there a possibility to have a cell, or a matrix with all the files found?
Thanks

See code samples in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

out = dir(fullfile(open_folder,'*.txt'))
This is much neater, faster, and less likely to have bugs than trying to do this in a loop. The usage of fullfile is good code though, so we will keep that!
If required you can sort/filter the strings in out as well, to remove other files that you do not want. You could use regexp for this.

The sorting takes place inside the loop? What sort of sorting are you doing (no pun intended)?
