METHOD OF QUADRATIC INTERPOLATION KELLER VANDEBOGERT 1. Introduction Interpolation methods are a common approach to the more general area of line search for optimization. In the case of quadratic inter-polation, the function’s critical value is bracketed, and a quadratic interpolant is tted to the arc contained in the interval. Then, the

motivates calling (2.7) the secant method, because it is just Newton’s method with the secant approximation of f00(x k) instead. 2.3. Method 3. Our third method is the 3 point method. Choose 3 points, 2 endpoints to bracket our critical point, and then a point within the interval as well. Using the Lagrange Interpolation formula, we can ...

For any given finite set of data points, there is only one polynomial of least possible degree that passes through all of them. Thus, it is appropriate to speak of the "Newton form", or Lagrange form, etc., of the interpolation polynomial. However, the way the polynomial is obtained matters. There are several similar methods, such as those of Gauss, Bessel and Stirling. They can be derived from Newton's by renaming the x-values of the data points, but in practice they are important.

Lagrange & Newton interpolation In this section, we shall study the polynomial interpolation in the form of Lagrange and Newton. Given a se-quence of (n +1) data points and a function f, the aim is to determine an n-th degree polynomial which interpol-ates f at these points. We shall resort to the notion of divided differences.

The Lagrange form of the interpolating polynomial is a linear combination of the given values. In many scenarios, an efficient and convenient polynomial interpolation is a linear combination of the given values, using previously known coefficients. Given a set of data points where each data point is a (position, value) pair and where no two positions are the same, the interpolation polynom…
