This m.file is intended to perform the numerical integration of a structural system subjected to an external dynamic excitation. The integration scheme utilized for this analysis is the newmark alpha-beta method.

it is a wavelet based code that will create the second order wavelet transform and subplot it in same image as shown in many matlab examples for wavelet transforms..

基于Logistic混沌映射的图像加密 将图像数据转换成二进制数据，并采用Logistic进行混沌序列生成，然后设定阈值将其转换成二值序列，之后，设定加密规则，将二进制图像数据与混沌二值序列进行加密运算，实现图像加密(Based on Logistic chaos mapping image encryption)

buck converter is used to steap down the voltage by varying duty cycle of operation

说明：  基于MATLAB平台实现两台主机（主机和客户端）之间的TCPIP通信，传递数据(the communication between server and client and then transfer data using TCPIP)

Matlab源码 计算矩阵各列与其他各列的互相关系数，并按照概率分布利用直方图的形式展示出来。 该互相关系数的定义参考Michael Elad的《Sparse and Redundant Representations》p25 Definition2.3(Matlab code for mutual-coherence of a given matrix)

物理层网络编码，也称为双向协同通信，采用的是BPSK加差分调制，主要分析系统的BER曲线(Physical layer network coding, also known as two-way collaborative communication, using BPSK differential modulation increases, the BER curve of the main analysis system)
