This result can be combined with subdivision method to obtain a piecewise intervalpolynomial approximation for a rational surface.
这一结果可以与细分技术相结合,得到有理曲面的分片区间多项式的逼近。

The perturbation ranges of the coefficients of Hurwitz polynomials, which is related to intervalpolynomial stability, are discussed, and three analysis methods are proposed.
The Fourier polynomial fitting is compared with the Chebysher polynomial fitting in the division of cyclic time interval and fitting accuracy as well as convergence of function.
