My question is what are the advantages of cubic spline interpolation over cubic Hermite interpolation?
WebPCHIP 1-D monotonic cubic interpolation. x and y are arrays of values used to approximate some function f, with y = f(x). The interpolant uses monotonic cubic splines to find the value of new points. (PCHIP stands for Piecewise Cubic Hermite Interpolating Polynomial). Parameters: x ndarray. A 1-D array of monotonically increasing real values. WebCreate a piecewise cubic monotone spline interpolation based on arbitrary points. This is a shape-preserving spline with continuous first derivative. if your data is already sorted in arrays, consider to use MathNet.Numerics.Interpolation.CubicSpline.InterpolatePchipSorted instead, which is more efficient. Parameters.
