I have attached a code below, which performs an operation. In the code below, i have done it with input as 8 digits. i want it with 128 digits. How can i use for loops and solve this issue?? for eg: here

x='11101101'
v='11001011'
Z='00000000'

But i want it for x=d9313225f88406e5a559......0000000 (128 digits each) {hexa decimal values}

x = '11101101';
v = '11001011';
Z = '00000000';
R = '10110111';
lsb=v(end);
w=xor(x-'0',v-'0');
   movex = @(z,a) [zeros(1,a) z(1:end-a)];
   q=movex(v,1);
   if x(1,1)==0
       Z1=Z;
  else
      w=xor(Z-'0',v-'0');
  end
   if lsb==0
       v1 = movex(v,1);
   else
       %k= xor([q{:}]-'0',[R{:}]-'0');
       k1=movex(v,1);
       k = xor(k1-'0',R-'0');
   end
