摘要
本文讨论代数多项式与三角多项式混合Ｌａｇｒａｎｇｅ插值问题，证明了这种插值问题的唯一可解性，给出了余项估计．数值算例表明这种插值方法的有效性．
This paper is concerned with the problem of algebraic trigonometric mixed Lagrange interpolation.This problem is proved to be solvable.The expression of the interpolation and the trancation error are given.Numerical examples show that the method is effective.
