Detailed Description

Ifpack_Polynomial: class for preconditioning with least squares polynomials in Ifpack.

The Ifpack_Polynomial class enables the construction of preconditioners based on least squares polynomials for an Epetra_RowMatrix. Similar to Ifpack_Chebyshev, Ifpack_Polynomial is designed for indefinite linear systems.

The list of parameters is

RealEigRatio_ = List.get("polynomial: real eigenvalue ratio", RealEigRatio_);
ImagEigRatio_ = List.get("polynomial: imag eigenvalue ratio", ImagEigRatio_); these are the ratios to estimate the bounds on the spectrum (if the eigenvalue bounds aren't already given)
LambdaRealMin_ = List.get("polynomial: min real part", LambdaRealMin_);
LambdaRealMax_ = List.get("polynomial: max real part", LambdaRealMax_);
LambdaImagMin_ = List.get("polynomial: min imag part", LambdaImagMin_);
LambdaImagMax_ = List.get("polynomial: max imag part", LambdaImagMax_); these values define the rectangular region on which the polynomial will be minimized.
PolyDegree_ = List.get("polynomial: degree",PolyDegree_); this is the polynomial degree.
LSPointsReal_ = List.get("polynomial: real interp points",LSPointsReal_);
LSPointsImag_ = List.get("polynomial: imag interp points",LSPointsImag_); these are the number of points used in real and imaginary directions which will be used in the least squares problem.
MinDiagonalValue_ = List.get("polynomial: min diagonal value", MinDiagonalValue_); this defines the threshold for diagonal values under which they are not inverted
ZeroStartingSolution_ = List.get("polynomial: zero starting solution", ZeroStartingSolution_); this flag allows to set a non-zero initial guess.
