Lagrange interpolation polynomial fitting
Lagrange interpolation polynomial fitting a set of points LAGRANG(X,Y,N,XX) where X and Y are row vector defining a set of N points uses Lagrange's method to find the N th order polynomial in X that passes through these points.
This program calculates and plots the Lagrange interpolation polynomial for a given set of data points. The Lagrange interpolation is a method to find an (n-1)th order polynomial that passes through n data points (x, y).
The input parameters for the program are:
- x: A row vector containing the x-coordinates of the data points.
- y: A row vector containing the y-coordinates of the data points.
- n: The number of data points.
- xx: A specific x-value to evaluate the interpolation polynomial.
