Abstract
En 中文
In this paper, we propose a new local construction of integro quartic splines which successfully works without any additional end conditions and without solving any system of equations. In fact, we obtain analytical formulae for values of the integro spline and up to its third-order derivatives values at the knots. Numerical experiments show our method is easy to implement and effective as well. (C) 2015 Elsevier Inc. All rights reserved.
