摘要
文章首先通过引进2个参数给出了基于块的二元混合有理插值的一般格式及其误差估计,并由这种一般格式得到4种不同的基于块的插值;应用基于块的二元混合有理插值方法给出了矩形网格上缺项的插值算法,并通过2个数值例子,验证了算法的有效性。
The general form of block-based bivariate blending rational interpolation with the error estimation is established by introducing two parameters. From this general form, four different block-based interpolations can be obtained. Then an efficient algorithm for computing bivariate lacunary rational interpolation is constructed based on block-based bivariate blending rational interpolation. At last, two numerical examples illustrate the validity of the method.
