C-2 Cubic Algebraic Hyperbolic Spline Interpolating Scheme by Means of Integral Values
MATHEMATICS(2022)
Abstract
In this paper, a cubic Hermite spline interpolating scheme reproducing both linear polynomials and hyperbolic functions is considered. The interpolating scheme is mainly defined by means of integral values over the subintervals of a partition of the function to be approximated, rather than the function and its first derivative values. The scheme provided is C-2 everywhere and yields optimal order. We provide some numerical tests to illustrate the good performance of the novel approximation scheme.
