摘要
提出了一种多项式插值的新方法 ,与拉格朗日插值相比较 ,推导更加简便 ,且具有显著的物理意义。同时 ,该方法将具有普遍意义的 m元 n次插值问题 。
A new method of polynomial interpolation is suggested in this paper. Compared with LaGrange interpolating method, the weighted method is both simpler in deduction and more significant in physics. Furthermore, this method also ascribes the interpolation issue with m independent variables and n powers to the research on the coefficient matrix of the linear system of equations about weighted coefficients.
