I am trying to update my array.i have an array ids which needs to be updated,whenever there is a new member(which is not present already in ids).Currently, i am using:
end
test = ismember(id_final,ids);%id_final is a temporary array
for k = 1:size(test,2)
if test(k) ==0
ids =cat(2,ids,id_final(k));
end
end
Is there some smart way to do this?
Please reply.

test = ismember(id_final,ids);%id_final is a temporary array
ids = [ids id_final(~test)];
Note: if the order of the ids is not important, just use
ids = union(ids, id_final);
