一种基于matlab的数字水印的仿真的实现。(Digital Watermarking Based on the simulation matlab implementation.)

模糊c均值聚类的一种改进算法，比较简单。用的时候先初始化一下，在不断迭代，参考里面的main函数吧。参考的时候去掉一些无关的命令，有些命令是我自己调用的无关的命令，可能目录里面没有，但不妨碍这个算法运行，可以屏蔽掉。(an improved fuzzy c means clustering algorithm)

基于传输矩阵法（TMM）计算VCSOA（垂直腔半导体光放大器）的稳态增益的程序。由于是从将输入端功率Pin作为已知条件，程序用Matlab优化工具箱中的fsolve函数计算了满足边界条件时的输出功率。这对于相关研究开发都是较好的资料。(This is a set of source codes, which are used for calculating the steady state gain of VCSOA based on the transfer matrix method(TMM). Since the input power of the VCSOA is regarded as a already-known condition, this program, the function "fsolve" in the Matlab Optimization Toolbox is used for obtaining the output power of the VCSOA when the input power is at some value. This is a good material for further studying the related problems, especially when using the Matlab for device simulations. )

它是基于matlab的语音分帧的代码，相信对大家理解有帮助。(It is based on the matlab voice sub-frames of the code, I believe we understand help.)

some useful definitions in project designs

this is the basic ofdm simulation of an ofdm signal

针对结构转角信息难以测量的问题，采用转角信息重构技术由随机子空间从振动信号中提取的结构平动位移估算结构转动位移，然后构建改进的单元损伤变量(Since it is difficult to measure the rotational responses of a structure, a technique was adopted to evaluate the approximate modal rotations with the modal displacements, which were extracted from structural vibrational signals with stochastic subspace identification, by static condensation and QR decomposition)

Adaptive Simulated Annealing with matlab code

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)

本程序包里面代码用matlab编写，有三个demo，分别处理然后用CS重建1维，2维信号，最后一个是对大脑图像做CS重建对比(This package inside the code written in matlab, there are three the demo, be treated separately and then use the CS reconstruction of one-dimensional, two-dimensional signal, the last CS reconstruction compared brain images)
