VecStrideScatter
Scatters a single component from a vector into a multi-component vector.
Synopsis
#include "petscvec.h"
int VecStrideScatter(Vec s,int start,Vec v,InsertMode addv)
Collective on Vec
Input Parameter
| s | - the single-component vector
|
| start | - starting point of the subvector (defined by a stride)
|
| addv | - one of ADD_VALUES,SET_VALUES,MAX_VALUES
|
Output Parameter
v -the location where the subvector is scattered (the multi-component vector)
Notes
One must call VecSetBlockSize() on the multi-component vector before this
routine to set the stride information, or use a vector created from a multicomponent DA.
The parallel layout of the vector and the subvector must be the same;
i.e., nlocal of v = stride*(nlocal of s)
