Logically Collective; No Fortran Support

Input Parameters#

  • vec - the vector

  • op - the name of the operation

  • f - the function that provides the operation.

Usage#

      PetscErrorCode userview(Vec,PetscViewer);
      PetscCall(VecCreateMPI(comm,m,M,&x));
      PetscCall(VecSetOperation(x,VECOP_VIEW,(void(*)(void))userview));

See the file include/petscvec.h for a complete list of matrix operations, which all have the form VECOP_, where is the name (in all capital letters) of the user interface routine (e.g., VecView() -> VECOP_VIEW).
