Not-A-Knot Cubic Spline Interpolation
Course: Computational Methods in Engineering (MAE 589)
Instructor: Dr. Hong Luo
Overview
This project implements not-a-knot cubic spline interpolation in FORTRAN as a stable alternative to high-degree polynomial interpolation.
Results
The method was validated with the Runge function and extended to parametric cubic splines for interpolating a circle from nine points. The study examines smoothness, accuracy, and error trends.
