On Interpolative Meshless Analysis of Orthotropic Elasticity
Buildings, 2023 As one possible alternative to the finite element method, the interpolation characteristic is a key property that meshless shape functions aspire to. Meanwhile, the interpolation meshless method can directly impose essential boundary conditions, which is

Symbolic-numeric sparse interpolation of multivariate polynomials [PDF]
Proceedings of the 2006 international symposium on Symbolic and algebraic computation, 2006 Prony's and other methods are used for symbolic interpolation using multivariate polynomials. The work includes an error analysis and an analysis of both the stability and the sensitivity of the process with the use of bounds on generalized eigenvalues. This is all for floating-point arithmetic and fixed precision.

On the numerical stability of linear barycentric rational interpolation [PDF]
Numerische Mathematik, 2022 AbstractThe barycentric forms of polynomial and rational interpolation have recently gained popularity, because they can be computed with simple, efficient, and numerically stable algorithms. In this paper, we show more generally that the evaluation of any function that can be expressed as$$r(x)=\sum _{i=0}^n a_i(x) f_i\big /\sum _{j=0}^m b_j(x)$$r(x)=∑
