Insert data in a cell

hello all,,

i've problem with my code about how to insert data in a cell's column

i mean like this

f =

    [1]    [4]     []    'low'

    [3]    [4]     []    'low' 

    [7]    [7]     []    'high'

    [7]    [4]     []    'high'

i want the result of my calculation --> length = ( b(:,1) - e(1,1)).^2 + (b(:,2) - e(1,2)).^2) included in the third column between [4] and 'low'

can someone help me?

i already try to fix the problem for 2 days

please help me

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

length is a built-in function. Don't use length as the name of your variable.

for i = 1:numel(length)
