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.
A=

You'll have to have A be character array or a string array, not a numerical array.
