Is there an easy way to get the result I want, that is, an interpolating function which is piecewise constant on the Voronoi cells of scattered ...

PIECEWISE POLYNOMIAL INTERPOLATION Recall the examples of higher degree polynomial in-terpolation of the function f(x)= ³ 1+x2 ´−1 on [−5,5]. The interpolants Pn(x) oscillated a great deal, whereas the function f(x) was nonoscillatory. To obtain interpolants that are better behaved, we look at other forms of interpolating functions ...

Piecewise linear interpolation is simply a game of connect-the-dots. Let us assume the nodes are given in order, so that t0 < t1 < ⋯ < tn. Between each pair of adjacent nodes, we use a straight line segment. The resulting interpolant p(x) is given by. p(x) = yk + yk + 1 − yk tk + 1 − tk (x − tk), for x ∈ [tk, tk + 1].

This table gives some values of an unknown function . Interpolation provides a means of estimating the function at intermediate points, such as . We describe some methods of interpolation, differing in such properties as: accuracy, cost, number of data points needed, and smoothness of the resulting

Does anyone know of a way to achieve either 0-degree spline or piecewise constant interpolation with Numpy/Scipy?

Piecewise Polynomial Interpolation §3.1 Piecewise Linear Interpolation §3.2 Piecewise Cubic Hermite Interpolation §3.3 Cubic Splines An important lesson from Chapter 2 is that high-degree polynomial interpolants at equally-spaced points should be avoided. This can pose a problem if we are to produce an accurate interpolant across a wide

What Is Interpolation?

Evaluate the speed of sound by piecewise-constant, left-endpoint interpolation of the (temperature, speed of sound) data of Table 1 at temperatures of 257K and 291K, respectively. We now wish to understand how well our interpolant If approximates f.

piecewise constant and piecewise linear interpolation of the time discrete solution. We provide elementary proofs of two crucial properties.
