K-mean-clustring

频率采样法的FIR数字滤波器的设计实现，嘿嘿(FIR digital filter)

这是一些文本聚类的matlab函数，是遗传算法过程中的一些常用函数(This is some text clustering matlab function, genetic algorithm is the process of some of the commonly used functions)

非参数的功率谱估计包括四个，周期图法，Blackman-Turkey,Welch-Bartell,改进的周期图法，输入信号为白噪声通过切比雪夫滤波后的信号(Non-parametric estimation of the power spectrum consists of four, periodogram, Blackman-Turkey, Welch-Bartell, improved cycle diagram method, the input signal is white noise ratio of the signal by cutting Schiff filtered)

wav格式的音频中实现水印的嵌入与提取 由现成的软件超级MP3转换大师V1.20把mp3->wav 然后再由MATLAB做wav水印嵌入 (wav audio format to achieve watermark embedding and extraction of off-the-shelf software from Super Master V1.20 to MP3 conversion mp3-> wav then wav watermark embedding MATLAB to do)

将core.txt文件放在C盘根目录下,然后打开matlab，点击“文件”-“打开”选中main.m文件，“运行”这个文件。 命令窗口马上就会显示出运行结果。 mm_Red.m为封装的盲目约简算法.返回值为约简结果. sxzyd_Red为封装的基于属性重要度约简算法.返回值为约简结果. bsjz_Red为封装的辨识矩阵约简算法.返回值为辨识矩阵和约简结果. cal_sig为封装的求属性重要度的函数。 max_min为封装的求属性度最大，划分个数最小的属性的函数。 dele_max为封装的删除属性度最大，划分个数最小的属性的函数。 mycore.m为封装的求核函数. myind为封装的求划分的函数. ind_E_a为求每个属性的划分的函数.(Files on the core.txt to the C root directory, then open matlab, click on " File" - " Open" main.m file is selected, " Run this file. The command window is displayed immediately run results. mm_Red.m the package blindly reduction algorithm. return value reduction results. sxzyd_Red degree reduction algorithm based on attributes important to package the return value is the result of the reduction. bsjz_Red matrix reduction algorithm for the identification of the package. return value identification matrix and reduction results. cal_sig package attribute importance to the function. max_min demand for the package attribute degrees largest division of the function of the minimum number of attributes. delete attribute degrees dele_max package is the largest division of the function of the minimum number of attributes. mycore.m seeking nuclear function package. myind package and by function. ind_E_a for the sake of each attribute divided function.)

多元线性回归算法，能将多个线性的物质之间的变量和自变量之间建立相关度高的线性回归方程。(Multiple linear regression algorithm, can the variables and between multiple linear material to set up linear regression equation with high correlation between independent variables. )

以幻灯片的形式讲解matlab应用.其中包含了例题所含的原程序.(The form of a slide on the matlab application. Which contains sample questions contained in the original procedure.)

这是一个造价预测的MATLAB程序，大家可以看看，还有待改进(This is a MATLAB program cost projections, we will look at have yet to be improved)

One of the significant drawback of OFDM system is the possibility to experience large peaks since the signal shows a random
