SNESLineSearchMonitorSet#

Sets an ADDITIONAL function that is to be used at every iteration of the nonlinear solver to display the iteration’s progress.

Synopsis#

#include "petscsnes.h" 
PetscErrorCode SNESLineSearchMonitorSet(SNESLineSearch ls, PetscErrorCode (*f)(SNESLineSearch, void *), void *mctx, PetscErrorCode (*monitordestroy)(void **))

Logically Collective

Input Parameters#

  • ls - the SNESLineSearch context

  • f - the monitor function

  • mctx - [optional] user-defined context for private data for the monitor routine (use NULL if no context is desired)

  • monitordestroy - [optional] routine that frees monitor context (may be NULL)

Note#

Several different monitoring routines may be set by calling SNESLineSearchMonitorSet() multiple times; all will be called in the order in which they were set.

Fortran Note#

Only a single monitor function can be set for each SNESLineSearch object
