Chapter 3 Interpolation - MathWorks
Interpolation is the process of de?ning a function that takes on speci?ed values atspeci?ed points This chapter concentrates on two closely related interpolants: thepiecewise cubic spline and the shape-preserving piecewise cubic named “pchip ” 3 1 The Interpolating Polynomial We all know that two points determine a straight line
Makima Piecewise Cubic Interpolation » Cleve’s Corner: Cleve Moler on
The Hermite interpolation problem has got a unique solution Proof The idea is the following: we use a modi˜cation of the Newton basis for Lagrange interpolation That will provide a basis of P m with respect to which the Hermite interpolation problem can be expressed as an invertible triangular system
1 Cubic Hermite Spline Interpolation
There are two methods of doing interpolation using cubic Hermite splines in Matlab The ?rst is the function pchip pp = pchip(x f(x)) pchip takes a vector of nodesxand the corresponding function valuesf(x) and produces a cubic Hermite spline in Matlab’s internal format One can then use ppval to evaluate the cubic Hermite spline over a

D = {d Re(d) > 0 and d < 3} — i e they point in the direction of ?p and have magnitudes commensurate with ?p the “good” PH quintic corresponds to the ++ choice of signs in the solution procedure criterion for “good” solution — absence of anti–parallel tangents relative to the “ordinary” cubic Hermite interpolant
LECTURE 5 HERMITE INTERPOLATING POLYNOMIALS
• Hermite interpolation passes through the f unction and its first derivatives at data points This results in a polynomial function of degree • Extrapolation is the use of an interpolating formula for locations which do not lie within the interval p N + 1 p + 1 N + 1 – 1

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
How to compute Hermite derivatives in MATLAB?
- MATLAB already has two cubic Hermite interpolation methods (see Cleve's blog Splines and Pchips): 'spline' computes the derivatives by imposing the constraint of continuous second derivatives (this guarantees a very smooth interpolation result),
What is cubic Hermite interpolation?
- Cubic Hermite interpolation provides an efficient and simple method for numerical approximation. Let be a partition of an interval . For , the cubic Hermite interpolant is (1) where . It is known that and . In data-fitting problems, the values are given data and the derivatives remain to be determined.
How to perform Hermitian interpolation?
- With the package Element1D, you can compute the shape functions for one-dimensional Lagrangian- and Hermitian-type elements. You perform Hermite interpolation by fitting a curve to both an ordinate (field variable) and its slope (its derivative with respect to the local coordinate) at nodal points.
What is the Hermite interpolating polynomial?
- The generated Hermite interpolating polynomial is closely related to the Newton polynomial, in that both are derived from the calculation of divided differences. However, the Hermite interpolating polynomial may also be computed without using divided differences, see Chinese remainder theorem § Hermite interpolation .
