摘要
研究了以拟插值算子作为工具,针对m阶B样条能表示任意m-1次多项式,利用最小二乘法的向量表示,并依据推导出来的w_j(f)的组合形式,求出了在L_p空间下B样条拟插值算子的逼近阶.
Based on the deduced combination of the wj（f）,this paper studies and obtains B-spline interpolation operator approximation and its approximation order in the Lp space by using the interpolation operator as a tool,aiming at m-order B-spline energy which can represent any m-1 order polynomial.
