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
