PCLMVMSetUpdateVec

Set the vector to be used as solution update for the internal LMVM matrix.

Synopsis

#include "petscpc.h" 
PetscErrorCode PCLMVMSetUpdateVec(PC pc, Vec X)

Input Parameters

• pc - The preconditioner

• X - Solution vector

Notes

This is only needed if you want the preconditioner to automatically update the internal matrix. It is called in some SNES implementations to update the preconditioner. The right-hand side of the linear system is used as function vector.
