Methods in numerical analysis. Includes: Lagrange interpolation, Chebyshev polynomials for optimal node spacing, iterative techniques to solve linear systems (Gauss-Seidel, Jacobi, SOR), SVD, PCA, and ...

A modification of the conventional Lagrange interpolator is proposed in this paper, that allows one to approximate a band-limited signal from its own nonuniform samples with high accuracy. The ...

This paper uses interpolation polynomial method to approximate Nonlinear System. The Interpolation polynomial adopted in this methodology is a combination of Lagrange’s interpolation polynomials, ...
