how to determine that all cell array value exists in other cell array?

Hello every one

I have a cell array

S=3×1 cell array

[ 29 56 62]

[34 40 62]

[48 52 7]

and other sequence of values in cell array

T{1} for examle:

1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74

Hiw can I check that all values in S are contain in T?

Thank you

To save anyone else who looks at this from the effort:

S = {[29 56 62];
     [34 40 62];
     [48 52  7]};

T = {[1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74]};

This does what I think you want:

S = {[29 56 62];
     [34 40 62];
     [48 52  7]};

T = {[1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74]};

allSinT = cellfun(@(x,y) all(ismember(x,y),2), S,repmat(T,size(S)))

allSinT = 3×1 logical array
   1
   1
   1

Hi @Mira le!

To check if all the values of S are contained in T, you can use the ismember function.

Here's the code to check if all values in S are contained in T{1} specifically:

all(ismember(S{1}, T{1}))

This will return a logical value of true if all the values in S{1} are contained in T{1} and false otherwise.

If you have multiple sequences in T and you need to check if all values in S are contained in any of them, you can use a loop like this:

all_included = false;
for i=1:length(T)
    if all(ismember(S{i}, T{i}))
        all_included = true;
        break;
    end
end

This will return a logical value of true in all_included if all the values in S are contained in any of the sequences in T, and false otherwise.

Hope this helps!
