VecStrideScatterAll#
Scatters all the single components from separate vectors into a multi-component vector.
Synopsis#
#include "petscvec.h"
PetscErrorCode VecStrideScatterAll(Vec s[], Vec v, InsertMode addv)
Collective
Input Parameters#
s - the location where the subvectors are stored
addv - one of
ADD_VALUES,INSERT_VALUES,MAX_VALUES
Output Parameter#
v - the multicomponent vector
Notes#
One must call VecSetBlockSize() before this routine to set the stride
information, or use a vector created from a multicomponent DMDA.
The parallel layout of the vector and the subvector must be the same; i.e., nlocal of v = stride*(nlocal of s)
Not optimized; could be easily
