The effects of rounding errors in the nodes on barycentric interpolation
arXiv:1309.7970
Abstract
We analyze the effects of rounding errors in the nodes on barycentric interpolation. These errors are particularly relevant for the first barycentric formula with the Chebyshev points of the second kind. Here, we propose a method for reducing them.
We fixed a few grammar errors and a minor mistake in Theorem 8: 2n + 5 was replaced by 2n + 6
