Detailed Description

template<typename Scalar, int Uplo = Eigen::Lower>
class Spectra::DenseSymMatProd< Scalar, Uplo >

This class defines the matrix-vector multiplication operation on a symmetric real matrix , i.e., calculating for any vector . It is mainly used in the SymEigsSolver eigen solver.
