A Concise Introduction to Numerical Analysis, 2018
Finite difference formulas Suppose you are given a data set of N non-equispaced points at x = x i with values f (x i) as shown in Figure 1. Because the data are not equispaced in general, then ∆x i = ∆x i+1. Figure 1: Data set of N points at x = x i with

Application of Fourier Truncation Method to Numerical Differentiation for Bivariate Functions
Comput. Methods Appl. Math., 2022The problem of numerical differentiation for periodic bivariate functions with finite smoothness is studied. To achieve stable approximations, we investigate some variants of the Fourier truncation method. Estimates of the accuracy and volume of the used

Numerical differentiation for two-dimensional functions by a Fourier extension method
Inverse Problems in Science and Engineering, 2020Based on the idea of Fourier extension, we develop a new method for numerical differentiation of two-dimensional functions on an arbitrary domain. The function will be extended to a periodic function on a larger domain. The Tikhonov regularization method
