Synopsis

#include "petscksp.h" 
PetscErrorCode PCRegister(const char sname[], PetscErrorCode (*function)(PC))

Input Parameters

• sname - name of a new user-defined solver

• function - routine to create method context

Example Usage

   PCRegister("my_solver", MySolverCreate);

Then, your solver can be chosen with the procedural interface via
