MATLAB: 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.

MATLAB

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

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

function y = mypolyval(c0,c,x)
if isempty(c)
  y = c0;
else
  y = c0 + power(x, 1:numel(c))*c(:);
end

The case y = c0 + c*x is already covered by the else. And you can use matrix multiplication of a row and a column vector r*c instead of sum(r.*c').

Replace

A=sort(x);
[A,T]=sort(x);
Q=R(T);

Q = Q(randperm(65536, 65536));

Then:

Q4 = reshape(Q, 4, 4, numel(Q)/16)

Now Q4(:, :, n) is the n.th matrix.
