KSPSetApplicationContext#
Sets the optional user-defined context for the linear solver.
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPSetApplicationContext(KSP ksp, void *ctx)
Logically Collective
Input Parameters#
ksp - the
KSPcontextctx - user context
Notes#
The user context is a way for users to attach any information to the KSP that they may need later when interacting with the KSP
Use KSPGetApplicationContext() to get access to the context at a later time.
Fortran Note#
This only works when ctx is a Fortran derived type (it cannot be a PetscObject), we recommend writing a Fortran interface definition for this
function that tells the Fortran compiler the derived data type that is passed in as the ctx argument. See KSPGetApplicationContext() for
an example.
