摘要
利用Euler Frobenius 多项式给出由基样条扦值所导出的有限差分方程的幂级数形式特解。
In this paper,the special solution with a power series form of finite difference equation which derived from Cardinal spline Interpolation was shown by taking advantage of EulerFrobenius polynomail.Furthermore,the asymptotic expansion form of the k fold cardinal splineonspline interpolation error was given, k =0(1)3.
