Detailed Description

template<typename Scalar>
class DenseGenComplexShiftSolve< Scalar >

This class defines the complex shift-solve operation on a general real matrix \(A\), i.e., calculating \(y=\mathrm{Re}\{(A-\sigma I)^{-1}x\}\) for any complex-valued \(\sigma\) and real-valued vector \(x\). It is mainly used in the GenEigsComplexShiftSolver eigen solver.

Constructor & Destructor Documentation

template<typename Scalar >

DenseGenComplexShiftSolve< Scalar >::DenseGenComplexShiftSolve ( ConstGenericMatrix & mat_ )

inline

Constructor to create the matrix operation object.

Parameters

mat_	An Eigen matrix object, whose type can be `Eigen::Matrix<Scalar, ...>` (e.g. `Eigen::MatrixXd` and `Eigen::MatrixXf`), or its mapped version (e.g. `Eigen::Map<Eigen::MatrixXd>`).
