PETSc version 3.17.4
TaoSetMonitor
Sets an ADDITIONAL function that is to be used at every iteration of the solver to display the iteration's progress.
Synopsis
#include "petsctao.h"
PetscErrorCode TaoSetMonitor(Tao tao, PetscErrorCode (*func)(Tao, void*), void *ctx,PetscErrorCode (*dest)(void**))
Logically Collective on Tao
Input Parameters
| tao | - the Tao solver context
|
| mymonitor | - monitoring routine
|
| mctx | - [optional] user-defined context for private data for the
monitor routine (may be NULL)
|
Calling sequence of mymonitor
PetscErrorCode mymonitor(Tao tao,void *mctx)
| tao | - the Tao solver context
|
| mctx | - [optional] monitoring context
|
Options Database Keys
| -tao_monitor | - sets TaoMonitorDefault()
|
| -tao_smonitor | - sets short monitor
|
| -tao_cmonitor | - same as smonitor plus constraint norm
|
| -tao_view_solution | - view solution at each iteration
|
| -tao_view_gradient | - view gradient at each iteration
|
| -tao_view_ls_residual | - view least-squares residual vector at each iteration
|
| -tao_cancelmonitors | - cancels all monitors that have been hardwired into a code by calls to TaoSetMonitor(), but does not cancel those set via the options database.
|
Notes
Several different monitoring routines may be set by calling
TaoSetMonitor() multiple times; all will be called in the
order in which they were set.
Fortran Notes
Only one monitor function may be set
