Find lagrange interpolation polynomial
WebJun 23, 2024 · Recently, the Leja points have shown great promise for use in sparse polynomial approximation methods in high dimensions (Chkifa et al., 2013; Narayan & Jakeman, 2014; Griebel & Oettershagen, 2016).The key property is that, by definition, a set of n Leja points is contained in the set of sizen + 1, a property that is not shared by other …
