Genetic Algorithm in MATLAB

一篇非常经典的LEACH协议改进文献，值得大家学习，在此与大家共享。(It is a very useful book that about LEACH protocol! You can study it and get you want.thank you!)

针对主成分分析的很实用的程序，只需要把所掌握的数据带入，就可以获得一系列的数据，包括相关矩阵、载重、主成分贡献率等。(Principal component analysis and practical program, simply put into the master data, you can get a range of data, including the correlation matrix, load, principal component contribution rate.)

此代码应用于将xml文件转换为mat文件。在图像的目标识别时我们需要获得一些图像的点坐标。但是通过label me。我们只能获得xml文件的形式，这样我们就需要将xml文件转换为mat文件。方便在matlab的语言环境中进行处理(This code is used in the xml file into mat file. When the target image recognition we need at some point in image coordinates. But by label me. We can only get in the form of xml files, so we need to convert the file to mat xml file. Facilitate processing matlab language environment)

Modfied version of SMOTE

图像加噪和去噪代码，读取图像数据，产生噪声图像，使用sym4小波进行三层分解(Images with noise and denoising code, read the image data, image noise, the use of three wavelet decomposition sym4)

正弦波脉宽调制技术（SPWM）三项pwm逆变器双极性SPWM波形的产生(Sinusoidal pulse width modulation (SPWM) three pwm inverter bipolar SPWM waveform generation)

用余弦法仿真的瑞利衰落，包括自相关互相关、功率谱密度等等。依据是Chengshan Xiao2003年的文章。(Cosine method for simulation of Rayleigh fading, including the auto-correlation cross-correlation, power spectral density and so on. Based on the the Chengshan Xiao2003 article.)

OMP算法，用于图像的重构过程中，比较经典，尤其是数字信号处理中(OMP algorithm for image reconstruction process, the more classic, especially in digital signal processing)

基于matlab的字母识别，基于模板匹配，因为采用区域生长法，速度可能有些慢！(Base on matlab!)
