Chebyshev polynomials of the first kind are defined as Tn(x) = cos (n*arccos (x)). These polynomials satisfy the recursion formula. Chebyshev polynomials of the first kind are orthogonal on the interval -1 ≤ x ≤ 1 with respect to the weight function . Chebyshev polynomials of the first kind are special cases of the Jacobi polynomials.

16.02.2017 · MatthewPeterKelly/C hebyshev_Polynomial s. Tutorial for function approximation with Chebyshev orthogonal polynomials, written in Matlab. Strongly inspired by the chebfun project ( www.chebfun.org ). These methods use barycentric interpolation, which allows for efficient computation and numerical stability, even for high-order approximations.
