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 Parameters#

  • 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.
