converged() [1/2]

template<typename F >

virtual uint eigensolver::GEVPSolver< F >::converged ( ) const

virtual

converged() [2/2]

virtual uint eigensolver::EigenSolver< Cmplx >::converged

pure virtualinherited

Returns the number of converged eigen pairs.

getEF()

template<typename F >

virtual const concepts::Array<concepts::Vector<Cmplx>*>& eigensolver::GEVPSolver< F >::getEF ( )

virtual

Implements eigensolver::EigenSolver< Cmplx >.

getEV()

template<typename F >

virtual const concepts::Array<Cmplx>& eigensolver::GEVPSolver< F >::getEV ( )

virtual

Returns an array with the eigen values.

Deprecated:

: this interface requires that the returned array must be hold as a member variable of the class.

(use std::auto_pointer or similar)

Implements eigensolver::EigenSolver< Cmplx >.
