let x&T two vector.now permute the x with T to get Y such that "y=x(t(n)).n is itration...next step???

A=[1 2 3;4 5 6;7 8 9]; B=A(:)'; x(1)=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 Q=sort(x); T=randperm(length(x)); Q(n)=x(T(n));

Please read How to format code in the forum. I do not understand the question.
