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 KSP context
ctx - optional 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#

To use this from Fortran you must write a Fortran interface definition for this function that tells Fortran the Fortran derived data type that you are passing in as the ctx argument.
