二阶非齐次线性常微分方程特解的算法模型

The Algorithm Model of A Special Solution to the Second-order Nonhomogeneous Linear Constant Coefficients Differential Equation

用迭代算法求二阶非齐次线性常微分方程y″ +py′+qy =pn(x)eαx=(AnXn+… +Aixi+… +Ao)eαx的特解是一种新的尝试 ,借助C + +BUILDER编译器成功地实现了该算法 。

This essay provides a recursive algorithm for a special solution to y″+py′+qy=P n(x)e ax and successfully realizes this calculating method by using C ++ Builder compiler,thus solving satisfactorily such practical calculating problems of getting special solution to differential equation.
