A= imread('camera man.png');
k=1:65536;
for I=1:256;
for j=1:256;
x=[0.3,zeros(1,65535)];
p=0.343;
for n=2:65536;
if x(n-1)>=0 & x(n-1)<=p
x(n)=x(n-1)/p;
else
x(n)=(1-x(n-1))/(1-p);
end
end
S=(x*255)+1;
Q=[0.2,zeros(1,65535)];
p=0.343;
for n=2:65536;
if Q(n-1)>=0 & Q(n-1)<=p
Q(n)=Q(n-1)/p;
else
Q(n)=(1-Q(n-1))/(1-p);
end
end
D=(Q*255)+1;
L=mod(S,8)+1;
P=mod(D,8)+1;
bits = bitget(A(I,j),[L,P]);
A(I,j)=bitor(bitset(A(I,j),[P,L],bits));
end
end

I have showed several of the problems in your other question.
These problems have nothing to do with the swapping of the bits. They're much earlier than that.
