Matlab unique rows cell array / table 将不同的排列视为相等
Matlab unique rows cell array / table considering different permutations as equal
给定一个包含两列的元胞数组（或 table），如何找到行中值的唯一排列？即给定A = {'a','b';'b','a';'c','d'}，应该返回的是{'a','b';'c','d'}.
A 是元胞数组这一事实使事情变得复杂。你可以这样做：
[~, ~, u] = unique(A); % get unique labels of cells
u = reshape(u,size(A)); % reshape into original shape
u = sort(u,2); % sort each row
[~, r] = unique(u, 'rows'); % indices of unique rows
result = A(r,:); % use those indices into input cell array
