Random combination between 2 arrays

Suppose I have 2 arrays

X1 = 2.23 2.90 3.04 3.81

X2 = 0.51 0.55 0.61 1.5

Now I have to make the random combination of both these arrays(X1 & X2) such that the element must not repeat like the one given below

(2.23, 0.55); (2.90, 1.5); (3.04, 0.61); (3.81, 0.5)

Thanks in advance..

X1 = [2.23  2.90  3.04  3.81];
X2 = [0.51  0.55   0.61  1.5];

output = [X1(randperm(4)); X2(randperm(4))].'

output = 4×2

3.0400 0.6100 2.9000 0.5500 2.2300 0.5100 3.8100 1.5000
