[petsc-users] VecStrideScatter question

[Tabrez Ali]

Hello

I have two parallel vectors (same layout) of different lengths, e.g.,

V1=[u1 v1 w1 u2 v2 w2 u3 v3 w3]' and
V2=[x1 x2 x3]'

and I wish to add them in a way such that

V3=[
u1
v1
w1+x1
u2
v2
w2+x2
u3
v3
w3+x3
]

Is VecStrideScatter appropriate for this? I tried

call VecStrideScatter(V2,3,V1,Add_Values,ierr)

but it seems to fail. Thanks in advance

Tabrez
