by using the generalized vadermonde matrix, we obtain a necessary and sufficient condition to judge the existence of the osculatory rational interpolating function and give its representation formula.
在此基础上借助于广义范德蒙矩阵,得到了切触有理插值存在性的充分必要条件。
for assigned interpolating condition, whether we can construct osculatory rational interpolating function just like constructing multinomial interpolating function is worth researching.
