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?

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.

Thank you.
I no longer have access to R2019a (and I prefer not to download it, since I almost never need to test code with it).
If my Answer helped to solve your problem, please Accept it!

oh sorry, by running it I meant it ran with no errors. But nothing shows up on the matricies when I test it with parent folders.

When I ran my version (that I posted), it ran without error and produced the correct result.
The problem may be with your paths and directories. I do not have access to it, so I cannot test my code with it.
