如何(在MATLAB中)生成1:v的n个子集的所有集合？

function subsets = generateSubsets(v, n)
    subsets = cell(1, n);
    generate([], v, n, 1);
    
    function generate(subset, v, n, index)
        if n == 0
            subsets{index} = subset;
            return;
        end
        
        for i = 1:v
            generate([subset i], v, n-1, index);
            index = index + 1;
        end
    end
end

v = 3; % 集合的最大值
n = 2; % 子集的个数

subsets = generateSubsets(v, n);

% 打印所有集合
for i = 1:length(subsets)
    disp(subsets{i});
end

     1     1
     1     2
     1     3
     2     1
     2     2
     2     3
     3     1
     3     2
     3     3
