EPSRegister

Adds a method to the eigenproblem solver package.

#include "slepceps.h" 
PetscErrorCode EPSRegister(const char *name,PetscErrorCode (*function)(EPS))

Not Collective

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

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

    EPSRegister("my_solver",MySolverCreate);

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

    EPSSetType(eps,"my_solver")

or at runtime via the option

    -eps_type my_solver
