Find the lagrange interpolating polynomial
WebJun 23, 2024 Β· 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 β¦ WebMar 23, 2024 Β· The Lagrange interpolation is a method to find an (n-1)th order polynomial that passes through n data points (x, y). The input parameters for the program are: x: A row vector containing the x-coordinates of the data points. y: A row vector containing the y-coordinates of the data points. n: The number of data points.
