NEPRegister

Adds a method to the nonlinear eigenproblem solver package.

#include "slepcnep.h" 
PetscErrorCode NEPRegister(const char *name,PetscErrorCode (*function)(NEP))

Not Collective

	name	- name of a new user-defined solver
	function	- routine to create the solver context

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

    NEPRegister("my_solver",MySolverCreate);

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

    NEPSetType(nep,"my_solver")

or at runtime via the option

    -nep_type my_solver
