MueLu::CutDrop Namespace Reference

Classes
class	UnscaledComparison
	Orders entries of row \(i\) by \(|A_{ij}|^2\). More...
class	ScaledComparison
	Orders entries of row \(i\) by \(\frac{|A_{ij}|^2}{|A_{ii}| |A_{jj}|}\). More...
class	UnscaledDistanceLaplacianComparison
class	ScaledDistanceLaplacianComparison
	Orders entries of row \(i\) by \(\frac{|d_{ij}|^2}{|d_{ii}| |d_{jj}|}\) where \(d_ij\) is the distance Laplacian. More...
class	CutDropFunctor
	Order each row by a criterion, compare the ratio of values and drop all entries once the ratio is below the threshold. More...
