VecRegister#

Adds a new vector component implementation

Synopsis#

#include "petscvec.h"  
PetscErrorCode VecRegister(const char sname[], PetscErrorCode (*function)(Vec))

Not Collective

Input Parameters#

  • sname - The name of a new user-defined creation routine

  • function - The creation routine

Notes#

VecRegister() may be called multiple times to add several user-defined vectors

Example Usage#

    VecRegister("my_vec",MyVectorCreate);

Then, your vector type can be chosen with the procedural interface via

    VecCreate(MPI_Comm, Vec *);
    VecSetType(Vec,"my_vector_name");

or at runtime via the option

    -vec_type my_vector_name
