摘要
本文对数学逼近理论中的Lagrange插值公式在一些特殊节点下进行了转型,使特殊情况下的计算量大大减少,从而使近似计算更为方便、高效。
In this paper,the Lagrange interpolation formula of approximation theory under special nodes is transformed.Thus the amount of calculation under special situation decreases greatly and the proximate calculation is more convenient and efficient.
