TaoMonitorSet#

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 TaoMonitorSet(Tao tao, PetscErrorCode (*func)(Tao, void *), void *ctx, PetscCtxDestroyFn *dest)

Logically Collective

tao - the Tao solver context
func - monitoring routine
ctx - [optional] user-defined context for private data for the monitor routine (may be NULL)
dest - [optional] function to destroy the context when the Tao is destroyed, see PetscCtxDestroyFn for the calling sequence

See TaoSetFromOptions() for a monitoring options.

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

Only one monitor function may be set
