MATLAB: Choose the 3 first lowest number in the cell after it sorted

cell

hello all,,
i wanna ask u about how to choose the 3 first lowest number in that cell after it sorted
this is my code
a= input ('Input Number of Data :');
for c=1:a
        int2 = ['Input The First Score - ',num2str(c),' :'];
        int3 = ['Input The Second Score - ',num2str(c),' :'];
        str = ['Input Category ke - ',num2str(c),' :'];
        b(c,1) = input(int2);  
        b(c,2) = input(int3);
        f{c,4} = input(str,'s');
    end;
   for d = 1 : 1
        int4= ['Input The First Data :'];
        int5 = ['Input The Second Data :'];
        e(d,1) = input(int4);  
        e(d,2) = input(int5);
   end;
    length = ( b(:,1) - e(1,1)).^2 + (b(:,2) - e(1,2)).^2
    for i = 1:size(b,1)
  for j = 1:2
    f{i,j} = b(i,j);
  end; 
end
[key, index] = sort([f{:, 2}]);
sorted_f = f(index, :);
can anyone help me?
please

Best Answer

sorted_f(end-2:end, :)
It is surprising, that Thorsten's [f{end-2:end, :}] replies 3 elements only and a column vector.
