<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br>
I'd like to check, whether for a Vec or a Mat the creation process (VecCrteate, VecSetSize, VecSetFromOptions or VecDuplicate or ...) has already been done or not, i.e. I'd like to check, wether the Vec or Mat is a valid object.<br>
Thanks,<br>
Hannes<br>
