求解微分方程（这里指的是常微分方程）指含有一次、二次、乃至高次微分未知数的方程。是解决偏微分方程、数理方程的基础。有许多特殊函数，都是为了无法得出多项函数或超越函数型式的解析解的微分方程而定义出来。这些特殊函数之所以重要，是因为它们描述了自然界中的某些现象，例如，电子的活动、鼓皮的振动、钟摆的摆动等等。(Solve differential equations (in this case is the ordinary differential equation) means containing one, two, and even high-differential equations unknowns. Is to solve the partial differential equations, mathematical equations based. There are many special functions, are not drawn to a number of functions or functions beyond the type of analytical solution of differential equations which define them. These special functions are important because they describe the nature of certain phenomena, for example, electronic activities, drum skin vibrations, pendulum swing, and so on. )

有井曲线作为输入可计算其地震波的衰减,针对EMD方法的不足,分析了该信号的时域、频域、倒谱，循环谱等。( There is a well attenuation curve as input to calculate its seismic waves, For lack of EMD, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc.)

matlab程序，演示了如何画出系统时域和频域的step相应(This demo shows how to plot the time and frequency responses)

说明：  1 运行DCA_simuMain.m开始仿真 2 菜单：导入参数 --》 按键分配时隙--》输入BS编号，查看其最佳服务小区对应的用户，在matlab命令窗口可以看到其时隙分配情况(A simulation run DCA_simuMain.m Start Menu 2: Import parameter- &quot button allocated time slot-&quot input BS number, to view their best serving cell corresponding to the user, in the matlab command window you can see the slot allocation)

1、顺序后退法特征选择算法 2、SFFS 特征选择算法 3、ISD算法 4、LLR算法 5、CZD算法(1, the order backward method of feature selection algorithm 2, SFFS feature selection algorithm 3, ISD algorithm 4, LLR algorithm 5, CZD algorithm)

复杂网络研究的不同之处在于首先从统计角度考察网络中大规模节点及其连接之间的性质，这些性质的不同意味着不同的网络内部结构，而网络内部结构的不同导致系统功能有所差异。 eeglab主要可将edf文件在matlab中转换为mat文件(EEG siganal )

本程序实现了对数极坐标的基本变换，可以在图像处理、稳像等领域进行应用(logpolar algorithm)

matlab的程序范例和教学指南 是快速掌握的好方法(Matlab model and the procedures for teaching guide is a quick grasp of the situation)
