      11
BNdog =
       4
       4
blnmynokta =
      11
for i = 1:length(DNdog)
    for j = 1:(length(blnmynokta))
        if (BNdog(i) == blnmynokta(j))
            A(i,j) = [1];
        elseif (DNdog(i) == blnmynokta(j)) 
             A(i,j) = [-1];
        end
    end
end
A =  
     0

This is simple with toeplitz:
>> nC = 3;
>> nR = 6;
>> vC = zeros(1,nC);
>> vR = zeros(1,nR);
>> vR(end-nC+1) = -1;
>> toeplitz(vR,vC)
