摘要
讨论了一类反周期函数在等距结点组上的双周期插值问题,结合函数所要满足的插值条件与该类反周期函数所满足的基础分解定理,再利用插值基函数的性质,给出插值问题解存在的充分必要条件,并得到相应条件下解的显式.
A kind of 2-periodic interpolation on a group of equidistant nodes by anti-periodic function is studied. The necessary and sufficient condition of solvability of 2-periodic anti-periodic interpolation problem is obtained through applying decomposition theorem and property of interpolation basic function,a result by interpolation is given at equal-distant nodal point sets,and the solution is obtained if it exists in the end.
