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.
