Hi everyone.
Suppose i have a column vector X=[1;2;5;7;8].Now i want randomly arrangement of the values of this vector.For example X1=[2,7,8,1,5] is one of such random arrangement.My purpose is to randomly movement of this vector values and then add it to another vector say Y in one of my simulation experiment.
THANKS WITH BEST WISHES

sorry now i took a better look here try this
X=[1;2;5;7;8];
n=length(X);
y = datasample(X,n,'Replace',false)

X = X(randperm(numel(X));
