VecCopy
Copies a vector. y <- x
Synopsis
#include "petscvec.h"
PetscErrorCode VecCopy(Vec x,Vec y)
Logically Collective on Vec
Input Parameter
x -the vector
Output Parameter
y -the copy
Notes
For default parallel PETSc vectors, both x and y must be distributed in
the same manner; local copies are done.
Developer Notes
PetscCheckSameTypeAndComm(x,1,y,2) is not used on these vectors because we allow one
of the vectors to be sequential and one to be parallel so long as both have the same
local sizes. This is used in some internal functions in PETSc.
