牛顿插值(Newton interpolation)MATLAB代码实现 利用差商定义,为了计算插值多项式我们先列出差商表,然后利用差商表第一列即可计算 先封装一个差商函数,降低我们后续编程难度(我们后面调用这差商函数) 我们先列出差商表寻找下规律再写代码 上图中给出了一些差商表的规律和我们编程需要注意的细节。 我们发现先编程用前-后(...

, by sorting and linear interpolation, cf. [33, Alg. 2]. We underline that the stepsize \(\tau\) is unique and strictly positive, since \({\mathcal {M}}_k\) is strictly convex and \(\delta {\mathbf {v}}\) is a descent direction for \({\mathcal {M}}_k\) at v. This ...
