Dev-C++平台下的模拟电子在电场中的运动仿真。可以作为系统仿真课程的典型案例学习不同数值积分方法对仿真的影响，同时也是数值计算中微分方程计算的一个入门案例。在此基础上，可以修改为复杂场中的粒子运动行为仿真，以及其它的微分方程方程组表述的复杂系统。比如动力学系统。-Dev-C++ simulation of analog electronic platform in the electric field of sports. Different numerical integration methods for simulation can be used as a typical case of system simulation curriculum learning is also an introductory case numerical differential equation computing calculations. On this basis, it is possible to modify the particle movement behavior in the complex field simulation, as well as other Differential Equations expressed in complex systems. Such as dynamical systems.
