VecSetType#

Builds a vector, for a particular vector implementation.

Synopsis#

#include "petscvec.h"  
PetscErrorCode VecSetType(Vec vec, VecType newType)

Collective

Input Parameters#

  • vec - The vector object

  • newType - The name of the vector type

Options Database Key#

  • -vec_type - Sets the vector type; use -help for a list of available types

Notes#

See VecType for available vector types (for instance, VECSEQ or VECMPI) Changing a vector to a new type will retain its old value if any.

Use VecDuplicate() or VecDuplicateVecs() to form additional vectors of the same type as an existing vector.
