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
