This is a personal passion project I created as a delve into Lagrange polynomials and interpolation. The program is designed for matplotlib, however notably the graph will only show with some sort of ...

High order and sparse layers in pytorch. Lagrange Polynomial, Piecewise Lagrange Polynomial, Piecewise Discontinuous Lagrange Polynomial (Chebyshev nodes) and Fourier Series layers of arbitrary order.

Abstract: Base on the Lagrange interpolation polynomial algorithm, the error analysis is discussed in this paper. Firstly, we derive the Lagrange interpolation ...

Department of Mathematics, University of Sargodha, Sargodha, Pakistan. There are two general classes of subdivision schemes, namely, approximating and interpolating schemes. The limit curve of an ...

Abstract: This paper considers interpolating matrix polynomials P(λ) in Lagrange and Hermite bases. A classical approach to investigating the polynomial eigenvalue problem P(λ) x = 0 is linearization, ...
