I was wondering about excluding folders from a dir struct that contain the words 'output'

I understand how to exclude the first couple of entries in the struct

d = dir(pathName);

d = d(~ismember({d.name},{'.','..'}));

but is there a way that I could maybe use regexpi() inorder to find folders that contain the key world then insert them into the second line above?

I was using d(~ismember({d.name},{'.','..'})) but now ".DS" folders are added to directories and this one doesn't remove it!

@Mehri Mehrnia: you could either remove all structure elements whose names start with '.':

d = d(~startsWith({d.name},'.'));

or specify the DIR match string to match the required file/folder names.

Try this:

valid_filenames = cellfun(@isfile,{d.name});                            % Eliminate ‘.’, ‘..’
dnew = d(valid_filenames);                                              % Without ‘.’, ‘..’
idx = cellfun(@(x)contains(x,'output'),{dnew.name}, 'Unif',0);          % True If ‘output’ Present
dnew_edited = dnew(~[idx{:}]);                                          % Files Without ‘output’ In File Names
dnames = {dnew_edited.name}';                                           % File Names Without ‘output’

This is deliberately not as efficient as it might be (some of these could be combined), in order to demonstrate all the intermediate steps, and to provide flexibility in the event other restrictions may be necessary.
