摘要
利用仅带端点导数的Hermite插值公式导出一类仅带端点导数的求积公式 ,然后用等距结点的复合求积方法 ,构造出复合求积公式 ,利用同一内结点上相邻区间公式中导数项的系数互相抵消这一特点 ,得出只含整个区间两端点上导数值的复合求积公式 .
By means of the Hermite interpolat formula with extreme point derivatives, a type formulas of composite numerial integration with only concern the derivatives of extreme points of integration interval is derived.When the derivative value of integrands on extreme point is calculated easily, this formulas can obtain an good accuracy.
