整理好的粒子图像分割及匹配集合程序

Principal component analysis (PCA) is a mathematical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of uncorrelated variables called principal components. The number of principal components is less than or equal to the number of original variables.

This program can be used for plotting wavelet function.

双向DCDC电路实现能量双向流通，电压电流双环控制(Bidirectional DCDC circuit realizes energy bidirectional flow, voltage and current double loop control.)

Matlab implementation of ID3 and NaiveBayes classifier. It also includes example dataset as well.

说明：  设计产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，使用矩形窗设计不同特性的数字滤波器对信号进行滤波处理，分析所设计滤波器(画出了频率特性曲线)，并对信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，同时设计出了一个友好的人机交互界面。(Designed to produce a continuous signal, including low frequency, medium frequency, high frequency components, its sampling, spectral analysis, using rectangular windows of different characteristics of digital filter design the signal filtering, analysis of the designed filter (to draw the frequency characteristic curve), and signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, the mean time, a friendly interactive interface.)

比较全面和系统地介绍萤火虫算法的原理和方法，并给出了比较通用的代码模式，是目前能找到的最全面的萤火虫算法的介绍。(More comprehensive and systematic introduction to the principles and methods of Firefly algorithm, and gives a more generic code mode, the firefly algorithm can find the most comprehensive introduction.)

基于独立成分分析混合图像盲源分离技术与研究(Technology and Research mixed image separation by Independent Component Analysis)

本程序采用的是基于matlab的PQ分解法潮流计算，程序主要分为三个部分：第一部分用于生成系统的节点导纳矩阵。第二部分主要进行潮流系统的迭代运算。第三部分主要用于对程序最后输出结果的计算，如电压的幅值，相角，功率分布等。(This procedure is used in matlab the PQ decomposition method based on flow calculation, the program is divided into three parts: The first part of the node admittance matrix used to generate the system. The second part of the iteration trend system. The third part is mainly used for the calculation of the final output of the program, such as the amplitude of the voltage, phase angle, power distribution.)

说明：  仿真未做出来，谁做出来了给我发一下，谢谢！(Simulation did not come out, who did it out to me, thank you!)

based on Newton method on load flow program that can help you better electrical system optimization
