End conditions for cubic spline interpolation
(1979)
A class of end conditions is derived for cubic spline interpolation at equally spaced knots. These conditions are in terms of function values at the knots and give rise to O(h4) spline approximations. © 1978, by Academic ...
Improved orders of approximation derived from interpolatory cubic splines
(1979)
Let s be a cubic spline, with equally spaced knots on [a, b] interpolating a given function y at the knots. The parameters which determine s are used to construct a piecewise defined polynomial P of degree four. It is shown ...
