# MATLAB: Insert data in a cell

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
        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
for i = 1:numel(length)  f{i, 3} = length(i);end
