Some modifications: cd is faster than pwd, the trailing file separator is not needed, fullfile is smarter than [cd, filesep, results], because it considers the already existing separator in e.g. "C:\":
subdirectories = dir(fullfile(cd, results));
If you want to exclude all files and folders starting with a dot -e.g. a common method under Unix:
subdirectories(strncmp({subdirectories.name}, '.', 1)) = [];
To remove only "." and "..":
subname = {subdirectories.name};
subname(strcmp(subname, '.')) = [];
subname(strcmp(subname, '..')) = [];
Although these two directories have been the first and second entries in the list in all of my tests under Windows95 to Windows7, Suse-Linux, MacOS7/8/9/X, AUX and AIX, I would not rely on this, but use astring comparison always.
