:orphan: # SNES_NORM_FINAL_ONLY Compute the function and its L2 norm on only the final iteration. ## Note For solvers that require the computation of the L2 norm of the function as part of the method, behaves exactly as `SNES_NORM_DEFAULT`. This method is useful when the function is gotten after `SNESSolve()` and used in subsequent computation for methods that do not need the norm computed during the rest of the solution procedure. ## See Also [](ch_snes), `SNESNormSchedule`, `SNES`, `SNESSetNormSchedule()`, `SNES_NORM_INITIAL_ONLY`, `SNES_NORM_INITIAL_FINAL_ONLY` ## Level advanced ## Location include/petscsnes.h --- [Edit on GitLab](https://gitlab.com/petsc/petsc/-/edit/release/include/petscsnes.h) [Index of all SNES routines](index.md) [Table of Contents for all manual pages](/manualpages/index.md) [Index of all manual pages](/manualpages/singleindex.md)
