# 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.
