内容简介
本书以一些模型问题为背景，借助于数学软件Maple，Mathematica及MATLAB，利用符号运算、图像表示和数值解法等手段，系统地介绍了（线性与非线性）微分方程的基本概念和基本方法。通过40多个实际模型的讨论，使读者对建模、求解、分析解所反映的性质这一过程进行全面的了解。利用Maple，Mathematica及MATLAB在图形显示、符号计算、数值计算方面的功能，定性地分析了微分方程解的性质，700余幅图将方向场、解曲线、相平面等概念形象直观地表示出来。另外，书中选配了1900余道习题供读者使用。本书可供学习数学建模或微分方程的学生作为参考书，对于从事计算与建模的科技人员，本书也具有很高的价值。
