matlab实现矩形脉冲和根升余弦脉冲的QPSK调制功率谱密度及不同信噪比信道下的星座图，直接运行main函数即可(Plot the power density spectrum of the transmitted signal (e.g., with the matlab function psd) with different pulse shapes. How is it affected if a root raised cosine pulse is chosen instead of a rectangular pulse shape? Study the signal constellation in the receiver for various values of Eb/N0 for the AWGN channel. )

应用粒子群优化算法优化bp网络的权值和阈值应用于故障诊断，程序可行，效果明显编写详细，注释清晰。(Application of particle swarm optimization algorithm to optimize the weights and thresholds of BP network is applied to fault diagnosis, the program is feasible, the effect is obvious, and the notes are clear.)

是一个应用matlab编写的基于pca读取人脸的人脸识别和人脸检测软件，是一个非常不错的人脸检测识别软件。希望对大家有用(Matlab is an application prepared by the pca read on the face and face recognition face detection software, is a very good face detection recognition software. We hope to useful)

本程序包，包括六个子程序，其功能内部都有注释。主要解决聚类分析问题。运行时六个子程序都要放在matlab根目录下。(This package includes six routines, their functions have internal comment. Cluster analysis is mainly to solve the problem. Six runtime routines should be placed under matlab root directory.)

本程序在matlab环境下，基于量子遗传算法对pid控制器进行优化控制,从而完成性能更优(The program in matlab environment, based on quantum genetic algorithm to optimize control of pid controller, thus completing the better performance)
