Use cell indexing expressions--

>> c={[rand(4,1),rand(4,1)]};  % presume the format described for some sample data
>> c{:}                        % the cell content 
ans =
          0.94          0.61
          0.46          0.56
          0.98          0.29
          0.20          0.79
>> c{:}(:,2)                % return column 2 only
ans =
          0.61
          0.56
          0.29
          0.79

"i did it but there is no answer and i got error"

What, specifically, was "it" and what was the error? Can't see your terminal from here and the crystal ball is back in the shop for repairs (yet again)...

And, of course, I guessed at what your original Q? was actually describing so show us what you actually have and had tried before if you hope for any meaningful answers.
