Hello everyone,<br><br>I have a problem with creating a new large vector via combining existing small vectors. Suppose I have two vectors v1 and v2 (size n-by-1) already. I want to have a new vector vout (size 2n-by-1) with vout(1:n) = v1 and vout(n+1:2*n) = v2. Is there any quick way to create vout with Petsc's built in functions? Thanks.<br>
<br>Best,<br>Xiangdong<br>
