说明：  潮流计算，使用PQ分解法，是一种比牛顿法更优越的潮流计算法，收敛速度更快，收敛精度与牛顿法相同(power flow of P-Q)

WiFi Direct直连，实现了直连，能正常检测链接，没问题(WiFi Direct Direct Connect, to achieve a straight, normal detection link, no problem)

Electric Vehicle Model

冈萨雷斯——数字图像处理第二版matlab ，非常有用的(Gonzalez- Digital Image Processing 2nd edition matlab, very useful)

说明：  这是一个小巧的指针类.在这里提供了两个主类CountedPtr和BackPtr,可以使用在任何环境中(This is a small target category. Here the two main categories CountedPtr BackPtr and can be used in any environment)

利用matlab进行数据拟合，有现成代码和案例数据。(Use of matlab for data fitting, have a ready-made code and case data. )

说明：  深度学习的NN神经网络，加了改进的梯度，自己可以下载数据测试，如有不懂请联系本人(Depth study of the neural network NN, plus improved gradient, you can download the data to test, if I do not understand, please contact)

matlab教程，适用于初学者，简明易懂。教程主要为matlab基础操作。(Matlab tutorial, it is suitable for beginners, concise, easy to understand. The main matlab tutorial for basic operations. )

在频率域实现信号的频移，然后再变换回时间域的信号(In the frequency domain, the frequency shift signal is achieved, and then transformed back into the time domain signal)

In the following figure is a system of two water tanks. Mass flow into the top tank at a fixed rate q0 and exits this tank through an orifice of area A1. This exit water then flows into a second tank which has an orifice of area A2 at its bottom. Each tank has constant cross section of area A, with A>>A1,A2. (a) Determine the ODE model which governs the heights z1 and z2 of water in the system. (b) Determine the equilibrium given a fixed rate q0. (c) Linearize the system model about the equilibrium. (d) Compare the step responses of the nonlinear model and linearized model by choosing reasonable system parameters. ( (b) Plot the flow v.s. pressure drop curve with the estimated c to validate your estimation
