摘要
介绍了M athem atica软件符号计算功能,并根据初值问题数值计算方法,运用了M athem atica进行符号运算,建立了一种解初值问题的符号计算方法,算例表明该方法计算简单,易程序化,计算结果比传统的数值方法优越.
The symbolic calculation functions of Mathematica software are introduced in this paper, and according to the numerical calculation method of initial problems, Mathematica software is applied to symbolic calculations. Thus a symbolic calculation method of initial problems is built up. The sample indicates that this method is simplified and easy to programme and that the results of calculations are superior to those by the numerical method.
