摘要
从构建二元Lagrange插值多项式出发,给出了积分域封闭的具有较高代数精确度的二元GAUSS数值积分公式,其代数精确度的定义和证明完善,实例计算结果良好.
Be based on binary Lagrange polynomial interpolation, the paper has presented the binary GAUSS Numerical Integrals in closed area that has better generality, and proves its algebraic precision. The example＇s results show well.
