Using randsample

% Create two sets 
a = rand(10,1) ;
b = rand(20,1) ; 
% Assign to s1, s2 randomly 
s1 = randsample(a,length(a)) ;
s2 = randsample(b,length(b)) ;

Using randperm

% Create two sets 
  a = rand(10,1) ;
  b = rand(20,1) ; 
  % Assign to s1, s2 randomly 
  s1 = a(randperm(length(a))) ;
  s2 =  b(randperm(length(b)))  ;

Hi! Thanks for the answer. But I need to randomly interchange the total 2 sets between other two sets. like, first a(set of 100 values) is assigned to s1 , b(a set of 100 values) assigned to s2 and in the next run it have to assign a to s2, b assigned to s1. And here a and b randomly generates 100 values with a's range (0,0.7) and b's range (0.7,1.2) Thanks in advance...

Change the dimensions accordingly in the code...
