This package implements several interpolation algorithms: Interpolation into a of dependent variables. Interpolation in one dimension using cubic splines. spapi(knork1,,knorkm,x1,,xm,y) returns the B-form of a tensor-product spline interpolant to gridded data. Here, each knorki is either a knot sequence, or else is a positive integer specifying the polynomial order to be used in the ith variable, thus leaving it to spapi to Simple Algorithms and Architectures for B-Spline Interpolation P. V. SANKAR AND L. A. FERRARI another one-dimensional interpolation along the columns. See Figs. 8 and 9 for zoom factors 4 and 8, B-spline interpolation algorithm requires only additions. Similarly, One Dimensional Spline Interpolation Algorithms - CRC Press Book Together with its compagnion volume this book presents a practical introduction to computing spline functions, the fundamental tools for fitting curves and surfaces in computer-aided design (CAD) and computer graphics. This module is concerned with a one-dimensional cubic spline s(x), Such a spline may be used to interpolate (pass exactly through) a given set of The procedure nag spline 1d auto fit implements an algorithm of this type. The spline-based scheme is shown to generate excessively noisy fields in these simulations. The two methods are then tested in a one-dimensional advection The algorithms for rational spline interpolation of surfaces however, the package also supports a compatible one-dimensional interpolation capability. Single knots at 1/3 and 2/3 establish a spline of three cubic polynomials meeting with C2 continuity. Triple knots at both ends of the interval ensure that the curve interpolates the end points. In mathematics, a spline is a special function defined piecewise polynomials. In interpolating The data may be either one-dimensional or multi-dimensional. Cubic spline interpolation on Euclidean space is a standard topic in numer- Indeed, this follows since the kernels of the 2 3 matrices are one dimensional. introduced a computational implementation of the algorithm. Keywords: cubic spline interpolation, one-dimensional function reconstruction, zero-crossings.

Adaptive interpolation algorithms uses a pixel--pixel approach for interpolation and generate images of good visual quality whereas non INTRODUCTION:#1 Two Dimensional Spline.

Solving one-dimensional hyperbolic telegraph equation using cubic B-spline quasi-interpolation Marzieh Dosti and Alireza Nazemi Abstract In this paper, the telegraph equation is solved numer-ically cubic B-spline quasi-interpolation.We obtain the numer-ical scheme, using the derivative of the quasi-interpolation a short description of one-dimensional B-spline is also given in Appendix 1. The usefulness of the presented interpolation algorithm has been confirmed the One spline method of third order and two spline methods of forth order, with difficulties for interpolation of data specially for two dimensional splines increase.
