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 an inner angle not greater than 2π we find the best interpolant, where the optimality is measured by the simplified radial error.

圆弧的最优参数插值

本文的目的是构造一个圆弧的二次参数多项式插值，其中将圆弧的两个边界点插值。对于内角比2更大的每单位圆弧π我们找到最好的插值，其中，所述最优由简化径向误差测量。
