how to create a relation b/w two vector by scrambling of vector. let two vector R & S then scrambled and vector T is formed.

R & S s.that s(i)=r(t(i))

Answer 1

[Walter Roberson]

t = randperm(length(r));
s = r(t);

x=0.3;
p=0.343;
for n=2:5;
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
%plot(x);
A=sort(x);
t=randperm(length(x))
A=x(t)

[Sultan Mehmood]

plzzz check this is it correct.

[Walter Roberson]

Looks plausible.

Answer 2

[Sultan Mehmood]

plz help me is it true for pixel permutation.

x=0.3;
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
plot(x);
A=sort(x);
T=randperm(length(x));
A(n)=x(T(n));
I = imread('camera man.png');
R = I(:,:,1);
Z = reshape(randperm(numel(R)),size(R));
P=Z(:);
Q=P';
Y=randperm(length(Q));
y(n)=Q(T(n));
