How can I fill my cell array?

Hello,

U is cell:

U =

1×2 cell array

[1×2 double] [1×2 double]

>> U{1}

ans =

1 2

>> U{2}

ans =

2 3

T= []

T has the union of element of U 1 2 3

S = {}; is empty in the first time

I want to test each value of T if exist in U and the coy U{ i } in S, my S will be:

S={ { 1 2 }, {{1 2} {2 3}}, {2 3} }

[dpb]

Show precisely how you think you built the output S array...

here is my try:

U{1} =  [1,2];
U{2} = [2,3];
T = [1,2,3];
S = {};
for i = 1:length(T)
    temp_cell = {};
    k=1;
    for j = 1:length(U)
        if ismember(T(i),U{j})
            temp_cell{k} = U{j};
            k=k+1;
        end
    end
    S{i} = temp_cell;
end

The only difference with what you explained in your question is that the elements in U are lists, not cells. (ismember() does not work on cells)
