VecDuplicate#
Creates a new vector of the same type as an existing vector.
Synopsis#
#include "petscvec.h"
PetscErrorCode VecDuplicate(Vec v, Vec *newv)
Collective
Input Parameter#
v - a vector to mimic
Output Parameter#
newv - location to put new vector
Notes#
VecDuplicate() DOES NOT COPY the vector entries, but rather allocates storage
for the new vector. Use VecCopy() to copy a vector.
Use VecDestroy() to free the space. Use VecDuplicateVecs() to get several
vectors.
