VecCreate#
Creates an empty vector object. The type can then be set with VecSetType()
, or VecSetFromOptions().
Synopsis#
#include "petscvec.h"
PetscErrorCode VecCreate(MPI_Comm comm, Vec *vec)
Collective
Input Parameter#
comm - The communicator for the vector object
Output Parameter#
vec - The vector object
Notes#
If you never call VecSetType()
or VecSetFromOptions()
it will generate an
error when you try to use the vector.
