KSPRegister#

Adds a method, KSPType, to the Krylov subspace solver package.

Synopsis#

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

Not Collective

Input Parameters#

  • sname - name of a new user-defined solver

  • function - routine to create method

Note#

KSPRegister() may be called multiple times to add several user-defined solvers.

Sample usage#

   KSPRegister("my_solver", MySolverCreate);

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

` KSPSetType`(ksp, "my_solver")

or at runtime via the option
