choose the 3 first lowest number in the cell after it sorted

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

sorted_f(end-2:end, :)

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

wait,,it's not working

when i test with other data the result is wrong

sorted_f =

    [3]    [4]    [ 9]    'low' 
    [1]    [4]    [13]    'low' 
    [7]    [7]    [16]    'high'
    [7]    [4]    [25]    'high'

this is sorted f's result

and this is wrong minimal value of ur command

    [1]    [4]    [13]    'low' 
    [7]    [7]    [16]    'high'
    [7]    [4]    [25]    'high'

the true result is

    [3]    [4]    [ 9]    'low' 
    [1]    [4]    [13]    'low' 
    [7]    [7]    [16]    'high'

as u see the command not give the true result

it just select three data from bottom

can u fix it?
