void quda::Eig_Solver::GrandSchm_test	(	cudaColorSpinorField &	psi,
		cudaColorSpinorField **	Eig_Vec,
		int	Nvec,
		double *	delta
	)

Do the GrandSchmit orthogonalization and check the orthogonality of eigen vectors

Definition at line 45 of file eig_solver.cpp.

virtual void quda::Eig_Solver::operator() ( double *  alpha, double *  beta, cudaColorSpinorField **  Eig_Vec, cudaColorSpinorField &  r, cudaColorSpinorField &  Apsi, int  k0, int  m  )

pure virtual

Implemented in quda::ImpRstLanczos, and quda::Lanczos.

void quda::Eig_Solver::PrintStats	(	const char *	name,
		int	k,
		const double &	r2,
		const double &	b2,
		const double &	hq2
	)

Not implemented yet!!!, Prints out the running statistics of the solver

Definition at line 38 of file eig_solver.cpp.

void quda::Eig_Solver::PrintSummary	(	const char *	name,
		int	k,
		const double &	r2,
		const double &	b2
	)

Prints out the summary of the solver convergence (requires a versbosity of QUDA_SUMMARIZE). Assumes QudaEigParam.true_res and QudaEigParam.true_res_hq has been set
