Classes
class	CPreconditioner< ScalarType >
	Abstract base class for defining a preconditioning operation. More...
class	CIdentityPreconditioner< ScalarType >
	No-op preconditioner used when Krylov solvers run without preconditioning. More...
class	CJacobiPreconditioner< ScalarType >
	Specialization of preconditioner that uses CSysMatrix class. More...
class	CILUPreconditioner< ScalarType >
	Specialization of preconditioner that uses CSysMatrix class. More...
class	CLU_SGSPreconditioner< ScalarType >
	Specialization of preconditioner that uses CSysMatrix class. More...
class	CLineletPreconditioner< ScalarType >
	Specialization of preconditioner that uses CSysMatrix class. More...
class	CPastixPreconditioner< ScalarType >
	Specialization of preconditioner that uses PaStiX to factorize a CSysMatrix. More...
class	CAbstractPreconditioner< ScalarType >
	Applies a std::function as the preconditioning operation. More...

Functions
template<class ScalarType , class Apply >
void	ApplyPreconditionerOnHost (const CSysVector< ScalarType > &u, CSysVector< ScalarType > &v, Apply &&apply)
	Applies a preconditioner that only has a host implementation to vectors that live on the device: bring the input down, apply, put the result back.
template<class ScalarType , class Apply >
void	ApplyPreconditionerOnDevice (const CSysVector< ScalarType > &u, CSysVector< ScalarType > &v, bool useCuda, Apply &&apply)
	Mirror of ApplyPreconditionerOnHost: applies a device preconditioner to host vectors.
