Populate listbox with only directories?

I am trying to populate a listbox with only the folder names (directories) in a folder. The code below does that, but there are some weird '.' and '..' directories. How would I get only the folders, and not those dots?

S = dir(path);
N = {S.name};
set(handles.listbox4,'String',N)

S = dir( pathName );
N = { S( [ S.isdir ] ).name };
N = N( ~cellfun( @(x) strcmp( x, '.' ) || strcmp( x, '..' ), N ) );
set(handles.listbox4,'String',N)

should work fine. Your method would also pick up files as well as directories. I assume from your title that you don't want that.
