Optimal parametric interpolants of circular arcs (1911.05425v1)
Published 13 Nov 2019 in math.NA and cs.NA
Abstract: The aim of this paper is a construction of quartic parametric polynomial interpolants of a circular arc, where two boundary points of a circular arc are interpolated. For every unit circular arc of inner angle not greater than $\pi$ we find the best interpolant, where the optimality is measured by the simplified radial error.
