question on generating random numbers

Here is my matlab code S{1,2} = [0,1,3,6];

S{1,5} = [0,2]

S{1,4} = [0,4,7]; The above code means that an arc say (1,2) has set [0,1,3,6] and arc(1,5) has set [0,2] and so on. I would like to create these sets randomly for each arc.( the sets should have integer numbers between 0-10). Please help!

k=100 % number of random arcs
out=arrayfun(@(x) sort(randperm(11,randi(10)+1)-1),1:k,'un',0);
celldisp(out)

Using random permutation can be helpful, start from this prototype :

 S=cell(10,1);
 for n=1:10
 S{n}=randperm(10);
 end

you can add an integer random number n to truncate S{i} each time .
