Detailed Description

template<typename T>
class lambda_lanczos::eigenpair_manager::EigenPairManager< T >

Class to manage calculated eigenpairs.

This class does: (1) keep only N largest (smallest) eigenvalues and correspoinding eigenvectors. (2) add new eigenpairs and examine whether some of them are kept or all of them are dropped by (1) (which determine whether more Lanczos iterations are required). (3) give reference to eigenvectors.
