How can i randomly move the values of a vector

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
