摘要
结合二元Thiele型插值分叉连分式和牛顿插值多项式,通过引入混合偏差商构造三元有理插值,进一步给出其特征定理和误差估计,最后给出数值算例.
The bivariate Thiele-type interpolating branched continued fractions and New-ton interpolation polynomials are combined. By introducing the so-called blending partial differences, a triple rational interpolation scheme is obtained. The characteristic theorem and error estimation are presented. Finally, an example is given.
