How to select element from vector

__Hi guys. I've got a vector (for exhample) A=[5,4,7,9,11,2,16] (generally vector may be bigger).

1. I want to take random element a1 from it (now vector A have size 1*7).

2. Then i want to take one more random element a2 from A with out of a1 !!

etc.

__So i want to take all elements from vector A.

__Can you give me a clue, how to do it in a simplest way.

__Thanks in advance!!

 A=[5,4,7,9,11,2,16]  ;
 idx = randperm(length(A))  ;
 iwant = A(idx)

__But how can i take one more random element a2 from vector A with out of a1 (you called it "iwant "). See opoint 2 of my question.

[KSSV]

iwant is randomly arranged from A. Run a loop on iwant and pick.

Thank you very much KSSV. I've finally got what you meant.
