The following code tutorial is mainly based on code provided by Jordi Warmenhoven. Thus, the results in a smooth curve (a straight line in the limit), and a smaller leads to a more rough curve. Specifically, the spline must be twice differentiable.

The solution for the above spline that minimizes the above loss is the natural cubic spline with knots at. Find the cubic spline interpolation at x 1.

Here Si(x) is the cubic polynomial that will be used on the subinterval xi, xi1.

interpolate.

To derive the solutions for the cubic spline, we assume the second derivation 0 at endpoints, which in turn provides a boundary condition that adds two equations to m-2 equations to make them solvable. interpolate.

Jul 18, 2021 The cubic spline interpolation is a piecewise continuous curve, passing through each of the values in the table. .

In addition, for cubic splines ((k3)) with 8 or more knots, the roots of the spline can be estimated (sproot).
