rational polynomial

This result can be combined with subdivision method to obtain a piecewise interval polynomial 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。

Every polynomial is differentiable, and so is every rational.

每个多项式都是可微的, 而每个有理函数也是如此.

In fact, this rational quartic spline is the successful generalization of quartic polynomial spline.

事实上, 这种有理插值样条曲线是C~ 2连续的四次多项式样条的成功推广.

Enlighened by the superposed algorithm of two element polynomial interpolation, we present a simple method of finding rational interpolation functions.
