How to select random numbers from array for creating new matrix?

I have b1 array. b1=[-3,-1,1,3,5];
I want to create 3x4 matrix by using random elements of b1 array.
So, one of expected outputs:
ans= -1 5 -3 1
1 -3 5 -3
3 5 1 3
Anyone can help?

Hi,
try:
b1=[-3,-1,1,3,5];
A = b1(randi(numel(b1),3,4))
possible result:
A =
1 -1 -3 3
-3 5 -3 3
-1 -3 3 1
Best regards
Stephan
