hey all
If i have following array:
{[1,7];[2,6,1];[7,1,3];[3,5]}
how can I compare each cell in this array with all other cells'values. for example for first cell [1,7] i have to compare it with all other cells and find common values. to compare with [2,6,1] we will get 1, to compare with [7,1,3] we will get [1,7] and with [3,5] we will get an empty cell. Similarly after this we will compare 2nd cell [2,6,1] with all cells in array.

Yes they have unique elements.. [2,6,1,1,6] is not possible

Do you need the comparison result? If not, I think this skips right to the final result
aL = 1:length(a);
for na = aL
finalResult{na} = intersect([a{na}],[a{setdiff(aL,na)}]);
end
This code is a bit obfuscated. But if it gives the result you expect, I can try to help you understand it if you need me to.
