I want to express the subtraction of a binary matrix as a negative number.

ex) = 00000000 - 00001001 = 10001001

Below is the code that I tried.

num = (0:9)';
num_ver = repmat(num,[1,length(num)]);
num_hor = num_ver';
num_comb = [num_hor(:),num_ver(:)];
A = zeros(size(num_comb,1),8);
for ii = 1:length(num_comb)
    str2 = dec2bin(-(num_comb(ii,:)),8);
    str2_ = [str2;'        '];
    A(ii,:) = str2num(str2_(:)');

In the case of addition and multiplication, the desired value was output.(sum,prod)

The output value I want is as follows.
