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
Input Parameters#
Calling sequence of func
#
PetscErrorCode func(Tao tao, void *ctx)
tao - the
Tao
solver contextctx - [optional] monitoring context
Calling sequence of dest
#
PetscErrorCode dest(void *ctx)
ctx - monitoring context
Options Database Keys#
-tao_monitor - sets the default monitor
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 Note#
Only one monitor function may be set
