Detailed Description

Base class for all EigenProblem solves. This simply defines standard interfaces so that different solvers can be used easily.

Member Function Documentation

◆ get_shift()

const double& oomph::EigenSolver::get_shift ( ) const

inline

Return the value of the shift (const version)

     {
       return Sigma_real;
     }

References Sigma_real.

◆ set_shift()

void oomph::EigenSolver::set_shift ( const double & shift_value )

inline

◆ solve_eigenproblem()

virtual void oomph::EigenSolver::solve_eigenproblem	(	Problem *const &	problem_pt,
		const int &	n_eval,
		Vector< std::complex< double >> &	eigenvalue,
		Vector< DoubleVector > &	eigenvector
	)

pure virtual

Actual eigensolver. This takes a pointer to a problem and returns a vector of complex numbers representing the eigenvalues and a corresponding vector of eigenvectors

Implemented in oomph::ANASAZI, oomph::LAPACK_QZ, and oomph::ARPACK.
