Classes
struct	Ikarus::GeneralizedSymEigenSolver< SolverType, MT >
struct	Ikarus::GeneralizedSymEigenSolver< EigenValueSolverType::Spectra, MT >
	This class implements a wrapper to the Spectra generalized eigen solver for square real symmetric matrices, i.e. to solve \( Ax = \lambda Bx\), where A is symmetric and B is positive definite. It calculates the full spectrum of eigenvalues. More...
struct	Ikarus::GeneralizedSymEigenSolver< EigenValueSolverType::Eigen, MT >
	This class implements a wrapper to the Eigen generalized eigen solver for square real symmetric matrices, i.e. to solve \( Ax = \lambda Bx\), where A is symmetric and B is positive definite. A and B have to be dense matrices. More...
struct	Ikarus::PartialGeneralizedSymEigenSolver< MT >
	This class implements a wrapper to the Spectra generalized eigen solver for square real symmetric matrices, i.e. to solve \( Ax = \lambda Bx\), where A is symmetric and B is positive definite. It calculates a selection of eigenvalues. At most \( n - 1 \), where \( n \) is the number of rows/cols of the matrices. More...

Enumerations
enum class	Ikarus::EigenValueSolverType { Ikarus::BEGIN , Ikarus::Spectra , Ikarus::Eigen , Ikarus::END }
	A strongly typed enum class representing the type of solver to use for the eigenvalue problem. More...
