利用matlab对无线传感器网络进行部署，并且部署了长方形的障碍物，模拟室内环境。(Using matlab to deploy wireless sensor networks, and deployed a rectangular obstacles, simulated indoor environment.)

Using Matlab for the study of control

依次阐述了非线性动力系统的建模，单自由度自治系统、单自由度非自治系统和多自由度系统的分析方法及动力学行为(Turn on the modeling of nonlinear dynamical systems, single degree of freedom autonomous system, single degree of freedom analysis methods and dynamic behavior of the non-autonomous system and multi-degree-of-freedom system)

本代码是《通信信号处理》课程的大作业相应的代码。主要是通信信号发射端的仿真，具体功能是：1. 产生任意长度的伪随机序列，将序列映射为I,Q两路的信号，2.均方根升余弦滤波器成型. 3.经过通带衰减为3dB的倾斜滤波器（模拟信道衰落效果）4.插零，半带滤波器升抽样。 5.NCO处理单元调制(This code is communication signal processing courses corresponding to the large code. Mainly is the simulation of the communication signal transmitter, the specific functions are: 1. Produce arbitrary length of the pseudo-random sequence, the sequence mapping for the I, Q two-way signal, 2. Raise the root-mean-square filter forming 3. After passband attenuation 3dB tilt filter (analog channel fading effect) 4. Insert zero, half-band filter l sampling. 5. NCO processing unit modulation)

说明：  雅克比迭代法求解方程组;雅克比迭代法就是众多迭代法中比较早且较简单的一种，其命名也是为纪念普鲁士著名数学家雅可比。雅克比迭代法的计算公式简单，每迭代一次只需计算一次矩阵和向量的乘法，且计算过程中原始矩阵A始终不变，比较容易并行计算。(Jacobian iterative method for solving equations Jacobi iteration is one of the earlier and simpler iteration methods, and its name is also in memory of Jacobi, a famous mathematician in Prussia. Jacobian iterative method has a simple calculation formula, each iteration only needs to calculate matrix and vector multiplication once, and the original matrix A is always the same in the calculation process, so it is easy to parallel calculation.)

该程序是同步中的相位估计方法，该方法可以估计不同参数下的相位大小。(synchronization is the process of phase estimation method, which can be estimated under different parameters of phase size.)

matlab web 技术，通过这个技术，能让不会使用matlab的人使用matlab(matlab web technology, the adoption of this technology, can not use matlab to use matlab)

Lead-Acid Battery This demo implements a model of a lead-acid battery cell using the Simscape™ language to implement the nonlinear equations of the equivalent circuit components. In this way, as opposed to modeling entirely in Simulink® , the connection between model components and the defining physical equations is more easily understood.

很好的matlab程序，大家可以关注一下，主要是做图像的检测的。。。。(Good matlab program, we can look at the main image detection. . . .)
