New Cubic B-Spline Approximation for Solving Linear Two-Point Boundary-Value Problems

Mathematics, 2021
In this study, we introduce a new cubic B-spline (CBS) approximation method to solve linear two-point boundary value problems (BVPs). This method is based on cubic B-spline basis functions with a new approximation for the second-order derivative.
