Parameters x ndarray. Therefore, a high-degree interpolation may be a poor predictor of the function between points, although the accuracy at the data points will be "perfect." Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Rather than finding cubic polynomials between subsequent pairs of data points, Lagrange polynomial interpolation finds a single polynomial that goes through all the data points. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. Lagrange Polynomial Interpolation¶. If the two known points are given by the coordinates {\displaystyle (x_{0},y_{0})} and {\displaystyle (x_{1},y_{1})}, the linear interpolant is the straight line between these points. LAGRANGE INTERPOLATION • Fit points with an degree polynomial • = exact function of which only discrete values are known and used to estab-lish an interpolating or approximating function • = approximating or interpolating function.

These functions all perform different forms of piecewise cubic Hermite interpolation. In particular, take interpolation nodes a x 0 < x 1 < < x n 1 < x n b and produce the interpolation polynomial P n(x) that interpolates f(x) at the given node points. This example demonstrates how to approximate a function with polynomials up to degree degree by using ridge regression. • Setting up a polynomial with a total of unknowns: • Procedure to develop Hermite interpolation: • Set up the interpolating polynomial • Implement constraints • Solve for unknown coefficients, , , • Note that Lagrange interpolation is a special case of Hermite interpolation ( , … The general form of the an \(n-1\) order Newton’s polynomial that goes through \(n\) points is: The complexity of Interpolation Search Technique Time Complexity: O(log2(log2 n)) for the average case, and O(n) for the worst case (when items are distributed exponentially) Space Complexity: O(1) The Lagrange interpolation formula is a way to find a polynomial which takes on certain values at arbitrary points. The more data points that are used in the interpolation, the higher the degree of the resulting polynomial, and therefore the greater oscillation it will exhibit between the data points. This is more suitable for manual calculations because, for example, additional points in the Lagrange interpolation require all basis polynomials to be recalculated.

The Lagrange interpolation formula is a way to find a polynomial which takes on certain values at arbitrary points. Each function differs in how it computes the slopes of the interpolant, leading to different behaviors when the underlying data has flat areas or undulations.
