__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!!

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