Lagrange interpolation of functions of generalized bounded variation
This paper estimates the rate of convergence for functions of generalized bounded variation by the Lagrange interpolation polynomials based on the zeros of the Jacobi polynomials. Meanwhile, the paper discusses what kind of condition implies that \(L_ n(f,x)-f(x)=O(1/n)\) ?
