一类反周期函数缺项插值问题的解
|
Abstract:
对一类反周期函数双周期插值问题进行分析,根据插值条件,结合基多项式的分解定理,建立相应的线性方程组,由克莱默法则给出插值问题有解的充分必要条件,并得到该条件下插值解的显式表达式.
The 2-periodic interpolation under antiperiodic trigonometric polynomials is considered. A series of linear equations are established by decomposing the basis polynomials of interpolation, and a sufficient and necessary condition is given based on the Cramer's rule and the explicit expression of the interpolation solution is obtained
