i want to diffuse the values Matrix ''C' by any substitution method. any simple method suggest me.

I = [12 23 34;23 45 56;12 34 58];
R = I(:)';
x=0.3;
p=0.343;
for n=2:9;
  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
A=sort(x);
[A,T]=sort(x);
Y=R(T);
C=reshape(Y,[3,3]);
