PCSetFromOptions#
Sets PC options from the options database.
Synopsis#
#include "petscpc.h"
PetscErrorCode PCSetFromOptions(PC pc)
Collective
Input Parameter#
pc - the preconditioner context
Options Database Key#
-pc_type - name of type, for example
bjacobi
Notes#
This routine must be called before PCSetUp() if the user is to be
allowed to set the preconditioner method from the options database.
This is called from KSPSetFromOptions() so rarely needs to be called directly
