Cubic hermite splines
WebThe endslopes of the cubic spline follow these rules: If x and y are vectors of the same size, then the not-a-knot end conditions are used. If x or y is a scalar, then it is expanded to have the same length as the other and the … WebCubic Hermite Spline,Numerical Computation, chapter 3, additional video no 3.To be viewed after the regular videos of chapter 3.Wen Shen, Penn State Universi...

WebFirst, we assign a parameter value t i to each point P i. The usual way to do this is to use chord-lengths -- you choose the t i values such that t i − t i − 1 = ‖ P i − P i − 1 ‖. Then you compute x as a function of t. The calculation is the one you already know, but it's just x = f ( t) instead of y = f ( x). WebThe cubic interpolant P ( x) is shape preserving. The slopes at the x j are chosen in such a way that P ( x) preserves the shape of the data and respects monotonicity. Therefore, on intervals where the data is monotonic, so is P ( x), and at points where the data has a local extremum, so does P ( x). Note
WebCreate a Hermite cubic spline interpolation from an unsorted set of (x,y) value pairs and their slope (first derivative). WARNING: Works in-place and can thus causes the data array to be reordered. CubicSpline InterpolateHermiteSorted(Double[] x, Double[] y, Double[] firstDerivatives) Create a Hermite cubic spline interpolation from a set of (x ... WebThe cubic Hermite spline is a third-degree spline, whose derivative has given values in nodes. For each node not only the function value is given, but its first derivative value too. Hermite's cubic spline has a continuous first derivative, but its second derivative is discontinuous. The interpolation accuracy is much better than in the ...
