<br>
I do not understand why the following code does not work when I
try to<br>
use vectorization (many trials)? <br>
<br>
What am I doing wrong ? <br>
<br>
Thanks <br>

Actually, what you want and try to do is unclear. Even members()
could be not appropriate.<br>
You can easily get an error even with your unvectorized version, as
soon as one of the v components will appears several times in A(:,1)<br>
