Hi all,
When using
PetscErrorCode VecScatterCreate(Vec xin,IS ix,Vec yin,IS iy,VecScatter *newctx)
I want to add those values of xin to the original values of yin.
Is there a way to do this without copy of yin?
I am not sure what you mean here. Do you want xin == yin?
No, I mean part of xin is going to be added to part of yin.
Alright. We do not make a copy of yin. Matt

Thanks!
