摘要
利用熟知的 Ｌａｇｒａｎｇｅ 插值公式可求得由 Ｖａｎｄｅｒｍ ｏｎｄｅ 行列式确定的 Ｖａｎｄｅｒｍ ｏｎｄｅ 函数矩阵的逆矩阵。
The inverse matrix of Vandermonde’s functional matrix is studied with Lagrange’s interpolation formula, and a formula for determining the inverse matrix of Vandermonde’s functional matrix is given. And some functional identical equalities that are hard proven normally are obtained here.
