Cubic spline is comprised from a sequence of cubic polynomials, so to draw the curve we have to approximate each partial cubic polynomial with the polyline.

... cubic spline interpolation. Suggestion: as before, solve the problem in its matrix form, recalling that you should use curve parametrization.

In meteorology, usually our time series and curves are smooth without wiggles. In most cases, Akima fits 1D data well, but can occasionally wiggle.

Example: Hermite cubic spline interpolation of 3 points: (x0, y0), (x1, y1), (x2, y2). The goal is to compute parametric expressions for f0, f1.

1D Spline example. Each cubic spline interval (the blue line) is determined such that itself and its first derivative are continuous across the red points ...

For another example, in paper by Ming-Jun Lai and Schumaker, we used C^1 quintic splines to find a smooth interpolatory spline surface to interpolate a set ...

Results of piecewise linear, cubic spline interpolation and nearestneighbor approximation for a set of data

The first is also known as a cardinal or canonical spline, the second is often solved by quadratic or cubic Bezier curves. Again see next figure for a ...

Actually regular 2-d cubic splines does a good job, without any need for Hermite or Coons, or invention of new functions. All partials here are zero, ...

I have not made much tests with cubic vs quadratic, because the difference is too small to be noticed visually. But the difference exists all the same.

... derivative values. Thus two more equations are required in order to obtain the unique solution in (7). The following is common choices for the end ...

(ii) Our schemes are applicable for both equally or unequally spaced data; meanwhile, the rational cubic spline of Duan et al. [7-9] requires that the data ...

For another example, we use C^1 cubic splines to interpolate the temperature values over various cities over the U.S. continent based on a triangulated ...
