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 on Vec Many br

Input Parameter

s - the location where the subvectors are stored Many br
addv - one of ADD_VALUES,INSERT_VALUES,MAX_VALUES Many br

Output Parameter

v -the multicomponent vector Many br

Notes

One must call VecSetBlockSize() before this routine to set the stride Many brinformation, or use a vector created from a multicomponent DMDA. Many br

The parallel layout of the vector and the subvector must be the same; Many bri.e., nlocal of v = stride*(nlocal of s) Many br

Not optimized; could be easily Many br

Many br
