VecCopy#
Copies a vector y = x
Synopsis#
#include "petscvec.h"
PetscErrorCode VecCopy(Vec x, Vec y)
Logically Collective
Input Parameter#
x - the vector
Output Parameter#
y - the copy
Note#
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.
