compare char (and empty elements) present in two cells

Hi! I need to compare char (and empty elements) present in two cells. I made this code which works but it gives me an 'error' when it compares two empty cell elements (position [3,1] in 'cell_1' and 'cell_2'). In this case it returns 0 (false), i.e. they are not identical. How can I solve it?

cell_1 = importdata("cell_1.mat");
cell_2 = importdata("cell_2.mat");

row = height(cell_1);
column = width(cell_1);

siz = [row,column];
matrix_check = cell(siz);

for X = 1:row
    for Y = 1:column

        A = cell_1{X,Y};
        B = cell_2{X,Y};      

%         if A == B
% 
%             tf = logical(1);
% 
%         else

            tf = strcmp(A,B);  % returns 1 (true) if the two are identical and 0 (false) otherwise
    
%         end

        matrix_check{X,Y} = tf;
    end
end

matrix_check = cell(siz);

You seem to have a bad habit of abusing cell storage for no apparent reason.

replace the problematic command with

tf = strcmp(char(A),char(B));
