DALocalToGlobalBegin

Adds values from the local (ghosted) vector into the global (nonghosted) vector.

Synopsis

#include "petscda.h"   
int DALocalToGlobalBegin(DA da,Vec l,Vec g)

Collective on DA

Input Parameters

	da	- the distributed array context
	l	- the local values

Output Parameter

g -the global vector

Notes

Use DALocalToGlobal() to discard the ghost point values

The global and local vectors used here need not be the same as those obtained from DACreateGlobalVector() and DACreateLocalVector(), BUT they must have the same parallel data layout; they could, for example, be obtained with VecDuplicate() from the DA originating vectors.
