MatLMVMSetJ0KSP#
Allows the user to provide a pre-configured KSP solver for the initial inverse-Jacobian approximation.
Synopsis#
#include "petscksp.h"
PetscErrorCode MatLMVMSetJ0KSP(Mat B, KSP J0ksp)
Input Parameters#
B - A
MATLMVMmatrixJ0ksp -
KSPsolver for the initial inverse-Jacobian application
Note#
The KSP solver should already contain all the operators
necessary to perform the inversion. The MATLMVM matrix only
calls KSPSolve() without changing any other options.
