How to find unique values

Hi! I have the cell array of strings 'a' (attached): it's composed by 65 rows and 9 columns. For every columns, I want to find the values repeated only one time. The final result must be a cell array of strings with 9 columns that contains these values:

Column1     Column2    Column3   Column4    Column5    Column6    Column7    Column8    Column9
   4           2          1         1          1          3          2          32         2
               3          3                    2                     3          1          4
                          4                    4                                2
                                                                                3

Can you help me? thanks

The ‘Uvals’ array should have the information you want:

D = load('cat cat matlab2.mat');
a = D.a;

non_empty = cellfun(@(x)~isempty(x), a);
[r,c] = find(non_empty);
for k1 = 1:max(c)
    idx = r(c == k1);
    vals = a(idx,k1);
    Uvals{k1} = unique(vals);                   % Unique Values
end
