WebAn identical experiment was performed using cubic spline interpolation, i.e. fitting a series of cubic splines through 3, 5, 7, etc. up to 29 points. The particular implementation of Lagrange interpolation used was ‘ Neville’s Modified Method’, described by MacLeod [3]. WebThe Lagrange form of the interpolation polynomial shows the linear character of polynomial interpolation and the uniqueness of the interpolation polynomial. Therefore, it is preferred in proofs and theoretical arguments. crystal script enniscorthy
