On the conditioning of the Newton formula for Lagrange interpolation

open access: yesJournal of Mathematical Analysis and Applications, 2022
The authors study the conditioning of the Newton formula for the interpolation polynomial. They expected that the Chebyshev points are the solutions of the problem, but the proofs are not available yet. They use the \(\mathfrak{R}\)-Leja points that give a good stability property for interpolation problems.

Inverse central ordering for the Newton interpolation formula

open access: yesNumerical Algorithms, 2022
AbstractAn inverse central ordering of the nodes is proposed for the Newton interpolation formula. This ordering may improve the stability for certain distributions of nodes. For equidistant nodes, an upper bound of the conditioning is provided.

Central orderings for the Newton interpolation formula [PDF]

open access: yesBIT Numerical Mathematics, 2019
The stability properties of the Newton interpolation formula depend on the order of the nodes and can be measured through a condition number. Increasing and Leja orderings have been previously considered (Carnicer et al. in J Approx Theory, 2017. https://doi.org/10.1016/j.jat.2017.07.005; Reichel in BIT 30:332–346, 1990).

Newton–Simpson-based predictor–corrector methods for milling chatter stability prediction [PDF]

open access: yesScientific Reports
Milling chatter, a form of self-excited vibration, can cause significant damage in machining and manufacturing processes. By selecting appropriate milling parameters, milling chatter can be effectively mitigated without sacrificing milling efficiency ...

Intelligent trapezoid and variable weight combination-based reconstructed GM model [PDF]

open access: yesHeliyon
The GM(1,1) model's prediction accuracy is significantly influenced by the accuracy of background value estimation. The traditional trapezoidal background value can only be applied to a specific data sequence.

A Two-Dimensional Variant of Newton’s Method and a Three-Point Hermite Interpolation: Fourth- and Eighth-Order Optimal Iterative Schemes

open access: yesMathematics, 2023
A nonlinear equation f(x)=0 is mathematically transformed to a coupled system of quasi-linear equations in the two-dimensional space. Then, a linearized approximation renders a fractional iterative scheme xn+1=xn−f(xn)/[a+bf(xn)], which requires one ...
