VecStrideScatter

Scatters a single component from a vector into a multi-component vector.

Synopsis

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.

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

Keywords

vector, subvector
