Matlab PCA主成分分析 一个比较好的matlab代码，非常有用(Matlab PCA PCA matlab code is a relatively good, very useful)

采用标量衍射理论，实现菲涅尔衍射和夫琅禾费衍射，对光波的波前传播和数字全息的应用有帮助。(Using scalar diffraction theory, Fresnel diffraction and the realization of Fraunhofer diffraction of light waves of wave-front propagation and the application of digital holography to help.)

着是一个MATLAB中的图形合并的程序，也有不完善的地方，请指教！(with MATLAB is a graphic merger procedures have imperfections, please enlighten! Thank you)

二进制通信系统的进行蒙特卡罗仿真程序，以正交信号为基础。当均值分别等于０，０.１，１.０，２．０时完成１００００个比特的仿真并求出误差概率。绘出理论误码率和蒙特拉罗仿真的差错率并进行比较这俩个结果，并绘出每个均值情况下判决器的１０００个接受信噪比抽样(Binary communication systems to carry out Monte-Carlo simulation procedures to orthogonal signal basis. When the mean, respectively, equivalent to 10,000 completed 0,0.1,1.0,2.0 bit error probability simulation and obtained. Mapping theory and蒙特拉罗BER simulation这俩error rate and compare results, and the mean circumstances of each mapped)

This is a steganography program using least significant bis to hide image in other image program

该程序实现了通信中16QAM的调制解调，并与理论误码率进行比较，证明仿真的正确性。(The program implements a 16QAM modulation and demodulation in a communication, with the theoretical bit error rate compared to prove the correctness of the simulation.)

这是解决优化问题的遗传算法压缩包，实用性强，可以应用于不同的专业领域。(This is a genetic algorithm to solve optimization problems compressed, practical, can be applied to different areas of expertise.)

利用EM算法实现高斯混合模型的优化，完成特征建模(Use of EM Algorithm to to achieve the the the optimization of of the Gaussian mixture model, to complete the Feature Modeling)

图像边缘检测，并有gui界面的设计 有matlab程序生成exe的部分内容(detection of the image edge and establish the gui)

程序实现ofdm系统中通过用选择性映射（SLM）来改善系统的峰均比（PAR）。减少较大功率峰值出现(Program ofdm system by using selective mapping (SLM) to improve the system of PAR (PAR). Reduce peak power greater)
