Looks like </div><div>DAGetAO may provide a mapping between DA vector layout and natural layout. Since I am not very familiar with programming using AO, just wanted to ask if there is a more efficient/easier way to copy from the naturally ordered vector to the DA vector before delving into AO. If I have to use AO, could you please redirect me to some related example.</div><div><br></div><div>Thanks in advance.</div><div><br></div><div>Khalid</div><div
