#include "petscsys.h" PetscErrorCode PetscObjectSetTabLevel(PetscObject obj,PetscInt tab)Not Collective
|obj||- any PETSc object, for example a Vec, Mat or KSP. Thus must be cast with a (PetscObject), for example, PetscObjectGetComm((PetscObject)mat,&comm);|
|tab||- the number of tabs|
Notes: this is used to manage the output from options that are imbedded in other objects. For example the KSP object inside a SNES object. By indenting each lower level further the heirarchy of objects is very clear.
