Chapter-2

matlab中用以矩阵的运算，对初学者，学习matlab中数据的处理由一定帮助(matrix operation in matlab for beginners to learn the processing of data by certain matlab help)

一种新型的功率因数校正的分析和控制，有详细的参数和实验结果(A new analysis of power factor correction and control, detailed parameters and experimental results)

基于微分器的PID控制，是自动控制的重要组成部分，有着广泛的应用。(Differentiator-based PID control, automatic control is an important part, has a wide range of applications.)

简单的萤火虫算法matlab实现，大家可以下载了看看，并且进行改进。(Simple firefly algorithm matlab realize, we can download a look, and make improvements.)

matlab学习资料大全很好用，非常详细(matlab learning materials useful, very detailed)

说明：  继续上次传的普通遗传算法，加入啦初始化和选择部分(Continue to the last mass of the general genetic algorithm, adding you to initialize and select some)

说明：  在matlab环境下讲视频文件读入，程frames状，基本上所有的视频格式都支持。(in Matlab environment Video document read, Cheng-frames, basically all the video formats are supported.)

HHT是历史上首次对Fourier变换的基本信号和频率定义作的创造性的改进。他们不再认为组成信号的基本信号是正弦信号,而是一种称为固有模态函数的信号(HHT is the first time in the history of the Fourier transform basic definition signals and frequencies for creative change Progressive. They will no longer signal that the basic component signal is sinusoidal signal, but as an intrinsic mode function signals)

svm的一种特征选择方法，基因选取算去，减少特征数量，减少运算时间，也可提高运算精度(svm a feature selection method, gene selection operator to reduce the number of features to reduce the computation time, but also can improve the calculation accuracy)

说明：  基于MATLAB实现的43个经典神经网络源代码，包括遗传算法、BP神经网络、RBF神经网络等。(Based on MATLAB to achieve 43 classic neural network source code, including genetic algorithm, BP neural network, RBF neural network.)
