摘要
充分运用再生核的技巧,给出了一类常微分方程边值问题的精确解的级数形式表达式,为了得到边值问题的近似解,描述了迭代解法并进行了理论分析。本方法的优点在于构造了新基底,绕过了求施密特正交化的麻烦。通过数值例子验证了该方法不仅有效而且高精度。
A series representation of exact solutions of a class of boundary value problems of ordinary differential equations is given by making good use of reproducing kernel techniques. For getting the approximate solution, A iterative method is presented and its theoretical analysis is done. The advantage of the method lies in employing a new basic function and avoiding to the Schmidt orthogonalization. Results of some numerical examples have demonstrated that the proposed approach is not only effectiveness but also possessing good accuracy.
