On Multivariate Lagrange Interpolation [PDF]
Mathematics of Computation, 1995 Lagrange interpolation by polynomials in several variables is studied through a finite difference approach. We establish an interpolation formula analogous to that of Newton and a remainder formula, both of them in terms of finite differences. We prove that the finite difference admits an integral representation involving simplex spline functions.

Some new kinds of interpolation formulas and its applications [PDF]
Mathematics and Computational Sciences, 2022 In this work, using the determination function, some new kinds of interpolation formulas are presented.These novel formulas are extensions of Lagrange interpolation. Error formula for these new kind of interpolation formulas are obtained.

Journal of Low Frequency Noise, Vibration and Active Control, 2020 This paper uses the Barycentric Lagrange interpolation method to explore the free vibration of a plate with the regular and irregular domain using the Chebyshev function, allowing us to consider multiple dimensions. From our results, it can be shown that

LAGRANGE INTERPOLATION ON TIME SCALES
Journal of Applied Analysis & Computation, 2022 Summary: In this paper, we introduce the Lagrange interpolation polynomials on time scales. We define an alternative type of interpolation functions called \(\sigma\)-Lagrange interpolation polynomials. We discuss some properties of these polynomials and show that on some special time scales, including the set of real numbers, these two types of ...

A new interpolation method based on satellite physical character in using IGS precise ephemeris
Geodesy and Geodynamics, 2014 Due to the deficiency of sliding Lagrange polynomial interpolation, the author proposes a new interpolation method, which considers the physical character of satellite movement in coordinate transformation and reasonable selection of interpolation ...

A new multiplier for Lagrange interpolation in constrained non linear optimization [PDF]
المجلة العراقية للعلوم الاحصائية, 2010 In this paper, we have investigated a new multiplier for the Lagrange interpolation by modifying the initial value of the multiplier in order to reduce the errors and avoid the use of arbitrary values for the initial .
