Monitors progress of the SNES solvers by calling VecView() for the residual at each iteration.
Synopsis#

PetscErrorCode SNESMonitorResidual(SNES snes, PetscInt its, PetscReal fgnorm, PetscViewerAndFormat *vf)
Collective
Input Parameters#
snes - the
SNEScontextits - iteration number
fgnorm - 2-norm of residual
dummy - a viewer
Options Database Key#
-snes_monitor_residual [ascii binary draw][:filename][:viewer format] - plots residual (not its norm) at each iteration
Note#
This is not called directly by users, rather one calls SNESMonitorSet(), with this function as an argument, to cause the monitor
to be used during the SNES solve.
