Interpolation of natural cubic spline [PDF]
International Journal of Mathematics and Mathematical Sciences, 1992 From the result in [1] it follows that there is a unique quadratic spline which bounds the same area as that of the function. The matching of the area for the cubic spline does not follow from the corresponding result proved in [2].

A rational cubic spline with tension [PDF]
Computer Aided Geometric Design, 1990 The authors present a description and analysis of a rational cubic spline with tension intended for computer-aided geometrical design. Its description provides the tension parameters which are used for manipulation of the shape of the curve. The rational cubic Hermite interpolant is introduced after some preliminary analysis.

Solving 2D-Poisson equation using modified cubic B-spline differential quadrature method
Ain Shams Engineering Journal, 2018 In this study a modified cubic B-spline differential quadrature method (MCBDQM) is used to solve the two dimensional Poisson equation. Using the cubic B-spline functions, explicit expressions of weighting coefficients for approximation of derivatives are

Journal of Approximation Theory, 2022 A new way to form cubic splines that provide interpolants with exactness of degree four is introduced. These cubic spline interpolants are calculated by using tridiagonal matrices which are totally nonnegative and positive definite, and those are very attractive features for the numerical methods.

Wind velocity data interpolation using a weighted cubic spline [PDF]
E3S Web of Conferences, 2023 To predict meteorological conditions, it is essential to construct interpolating functions considering the nature of the data. The paper addresses an algorithm for constructing a weighted cubic spline that preserves the monotonicity of the data.
