Is there any command similar to setdiff for case insensitive. As setdiff is case sensitive?
for example a = {'car','book,'glass'}
b = {'CAr','book','glass'}
c = setdiff(a,b)
returns the same array a(because setdiff does not work for car insensitive)
how can i do this? because i have two cell array which is really large.
running in loop by strcmpi and finding the index will take some time.
is it possible to excute in single command as like setdiff?
Thank you

Hi,
if two commands is fine as well, you can do the following:
% find index of elements in a that are in b:
[flag,idx] = ismember(lower(a), lower(b));
% remove the found elements:
a(idx(flag)) = [];
