Classes
struct	FilteredLanczosOptions
	An instance of this class, taken by FilteredLanczosEigenSolver(), is a collection of options for the filtered Lanczos procedure to solve symmetric eigenvalue problems. More...
struct	FilteredLanczosInfo
	FilteredLanczosEigenSolver() returns an instance of this class which gives the information of the filtered Lanczos procedure. More...

Functions
FilteredLanczosInfo	FilteredLanczosEigenSolver (Vector &eigVal, Matrix &eigVec, const SparseMatrix &S, Vector &frame, mkIndex polyDegree, mkIndex baseDegree, FilteredLanczosOptions &opts)
