摘要
利用有限元和矩阵函数的有关理论与变系数等效参数相结合,提出了一种求解变系数微分方程的解法,利用它能方便地处理由于各种原因导致其控制方程是变系数的微分方程,最后通过两个算例。
Based on a method of finite element model and combined with matrix theory, a method for solving differential equations with variable coefficients is proposed.With that method,it is easy to deal with the differential equations with variable coefficients.On most occasions,due to the non_uniformity nature,non_linearity property can cause the kind equations.Using that model ,the satisfactory valuable results with only a few units can be obtained.
