why ismember({​struct.nam​e},{'*.mat​'}) returns zero while struct.nam​e='baseval​ues_Mean_r​.mat'?

Any idea why ismemeber returns zero in this case?

ismember() never does wildcarding. It only does exact matches.

regexp() does matching but the handling of wildcards is different than what you would expect.

~cellfun(@isempty, regexp({struct.name},'.*\.mat$', 'once'))

but for your purposes it might be enough to use

endsWith({S.name},'.mat')
