人脸识别matlab代码，可判断是否是库里的人(Face recognition MATLAB code)

快速傅立叶变换的补0问题 相信会对大家有帮助 CNKI的浏览器可以打开(Fast Fourier Transform Regrant 0 issues we believe will help CNKI browser can open)

主成分分析代码， 可以用于图像压缩等等，也叫PCAH或者KL变换(PCA or K_L transfer)

一种无线传感网络的LEACH分簇算法，大家都比较需要 (Wireless sensor networks LEACH clustering algorithm )

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.
