one's and two's complement

how to convert 8 bit binary numbers into one's and two's complement

Let a=11001011

ones_complement=00110100

twos_complement=00110101

Answer 1

a='11001011';
c1=not(a-'0')   % one's complement
d=1;
for k=numel(a):-1:1
  r=d & c1(k);
  c2(1,k)=xor(d,c1(k));  % c2 is two's complement
  d=r;
end
[c1;c2]

Answer 2

[MD SAMIM AKTAR]

a='11001011';

c1=not(a-'0') % one's complement

d=1;

for k=numel(a):-1:1

r=d & c1(k);

c2(1,k)=xor(d,c1(k)); % c2 is two's complement

d=r;

end

[c1;c2]
