FFT

这是一个用matlab编写的C4.5算法的实现(this is a classification of machine learing,C4.5,using matlab)

说明：  使用FFT分析方波信号的频谱，讨论采样点数、采样频率对谱分辨率的影响。对数据叠加白噪声后再次分析实验结果。(Square-wave signal using the FFT spectrum analysis to discuss the sampling points, the sampling frequency of the impact of spectral resolution. White noise superimposed on the data after analysis of experimental results.)

首先在m脚本文件canshuo.m中输入节点个数和路径权重，在命令窗口中输入canshu，用s=12,e=10的格式输入要求的起止点，再输入main即可得到两点之间的路径和长度。(M script file canshuo.m first enter the node number and the right path lies in the command window enter canshu, with s = 12, e = 10 The format of the input requirements of the start and end points, and then enter the main between two points can be obtained path and length.)

一些图像处理的小程序，有缩放，边缘提取，图像剪切等，希望对学习matlab图像初学者有所帮助(some small image processing procedures, zoom, edge extraction, image shear. hope to study images Matlab help beginners)

MATLAB遗传算法程序，主要用来求函数的极大值，可以修改后做其他的遗传算法方面的仿真(MATLAB genetic algorithm, the main function is to seek maximum value, after the simulation can be modified to do other aspects of genetic algorithms)

改代码为基于Konhone网络的分类算法，是MATLAB人工智能的经典算法(Change the code based classification algorithm Konhone networks, artificial intelligence is a classical algorithm MATLAB)

Program a. Description: This source code program can produce a minimum-length trajectory for any two configurations. b. Size: 28kb c. Platform: Matlab 7.1. d. Major Component Description: 41 .m files in the folder .Program

该MATLAB程序实现语音端点检测,能够检测出一个音频文件中的话音部分(This MATLAB program realizes the voice activity detection )

根据输入的电路矩阵表示形式，形成节点导纳矩阵，形成因子表的过程可以看做是规格化运算和消去运算的重复过程，重复的次数和非基准点的节点个数相同。 每个过程中进行的操作都相同，首先，存储规格化因子及消去因子；其次，对本行进行规格化运算，并将其值存储在因子表中；然后，对其后的每行进行消去运算；如此循环n次得到因子表。(Representation of the input of the circuit matrix, forming a node admittance matrix formation process can be seen as a factor table normalization process operations and eliminate duplicate operations, the same number of nodes and the number of repetitions of non-reference point. Each operation carried out during the same, first of all, storage and elimination factor normalization factor secondly, the Bank normalized operations, and its value is stored in the factor table then, each row will be erased after their operation so the cycle n times to get factor table.)
