Matlab 实现求复杂网络的度分布，并返回度，以及平均度(Matlab seeking to achieve the degree distribution of complex networks)

这是2dof（pi-逆前馈加pid反馈），单纯pid反馈，单纯pi模型逆前馈对应的仿真结果。 其中系统模型采用前面根据pi模型与n4sid算法结合得到的综合模型。(This is 2 dof (PI- inverse feedforward pid feedback), pure pid feedback, pure PI inverse model feed-forward corresponding simulation results. In front of the system model using models based on PI and n4sid algorithm combined with integrated model.)

说明：  主要介绍了90个MATALAB的一些基本用法实例，以M函数的形式给出程序的基本实现流程，适合于MATALAB的初学者，可在参考这些程序的基础上自己编程实现相应的功能。(90 MATALAB introduces some basic usage examples to M functions given in the form of the basic program implementation process, suitable for beginners MATALAB can refer to these programs based on their corresponding features programming.)

这是一个普通的、容易理解的卡尔曼跟踪滤波器的程序，对初学者有较大的帮助(This is a common, easy to understand the procedure of the Kalman tracking filter, a great help for beginners)
