# SNES_NORM_FINAL_ONLY

Compute the function and its L2 norm on only the final iteration.

### Notes

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.
