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, PetscErrorCode (*dest)(void **))

Logically Collective

Input Parameters#

  • 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

Calling sequence of func#

  • tao - the Tao solver context

  • ctx - [optional] monitoring context

Calling sequence of dest#

  • ctx - monitoring context

Notes#

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.

Fortran Notes#

Only one monitor function may be set
