On Polynomial Approximation in the Uniform Norm by the Discrete Least Squares Method.
Abstract
The discrete least squares method is convenient for computing polynomial approximations to functions. We investigate the possibility of using this method to obtain polynomial approximants good in the uniform norm, and describe applications both to the case when the function to be approximated s known on a discrete point set only and to the case when we can freely choose the set of least squares nodes. Numerical examples are presented.
