摘要
利用ＥｕｌｅｒＦｒｏｂｅｎｉｕｓ多项式和中点指数ＥｕｌｅｒＦｒｏｂｅｎｉｕｓ多项式给出有限差分方程的幂级数形式的特解，从而进一步给出偶次叠基样条插值误差的渐近展开形式．
In this paper, the special solution with a power series form of finite difference equations was shown by taking advantage of EulerFrobenius polynomial and middle power index EulerFrobenius Polynomial, furthermore, the asymptotic expansion form of even cardinal splinesonsplines interpolation error was given.
