M = sortrows(list);
out = M(sum(squeeze(any(M - permute(M,[3,2,1]) <= 0,2))) == 1:size(list,1),:);
[days] = out(:,1);

Hi Yannick Leroy,
the function ismember() allows to compare matrices with vector elements. The function find() supplies the indices. You don't need to use find() if you can utilize logical indexing.
[ind,~] = find(ismember(list,days)) % find row index only
ind = unique(ind); % remove duplicates
Kind regards,
Robert
