Multiscale M decision tree

jpeg压缩与解压例子，matlab中离散余弦变换并用huffman编码(jpeg compression and decompression example, matlab and used in the discrete cosine transform coding huffman)

说明：  六个傅里叶变换的例子，包括DFT，DTFT等(Fourier transform of the six examples, including DFT, DTFT, etc.)

这是＜小波分析与信号处理——理论、应用及软件实现＞的电子版书籍(<wavelet analysis and signal processing-- Theory, Application and Software> electronic version of books)

实现图像的同态滤波，但是在使用之前需要将图片替换成自己的图片，并且要将图片转换成灰度图片(Achieve homomorphic filtering of the image, but need to be replaced before using the pictures into your own picture, and you want to convert the picture into a grayscale picture)

说明：  观察数据长度N的变化对DTFT分辨率的影响 这几个程序是老师写的 对于理解DTFT有很大帮助(Effect of observation data length N on DTFT resolution These programs are written by the teacher and are very helpful for understanding DTFT.)

说明：  MUSIC方法是Schmidt 在 1979 年首先提出的,并于1986 年重新发表。该方法和 Roy 于1986 年提出的 Esprit方法都是早期经典的超分辨率 DOA 估计方法 即超瑞利限的方法 ,他们同属特征结构的子空间方法。(MUSIC method is Schmidt first proposed in 1979, and re-released in 1986. The method and Roy in 1986, Esprit proposed methods are early classic super-resolution DOA estimation method that is super-Rayleigh limit of the method, they belong to the same characteristic structure of the subspace method.)

project on SRM drive system The file is a Matlab m-file with all of the input parameters for the two Simulink models and It must be run prior to running the Simulink models to create the input parameters in the Matlab workspace. Because it is a Matlab m-file, it can be opened to change model input parameters. Once you have changed a parameter in you must run it again before you run the Simulink model to update the Matlab workspace and have the change take effect. The file is a Matlab m-file with all of the input parameters for the Simulink model.

小波分析，用于时间序列的周期性分析，更换函数即可使用(Wavelet analysis is used for periodic analysis of time series, and can be used to replace functions.)

使用matlab实现对语音文件的分析、处理并提取出mfcc参数(Matlab is used to analyze and process voice files and extract MFCC parameters.)
