《matlab扩展编程》语音处理部分的光盘程序("Matlab expansion program" part of the voice processing procedures CD)

將灰階圖形的像素黑白狀態記錄在音頻頻帶的peak改變上已將圖形資訊隱藏在音頻資料中.並提供灰階圖形資料的取出方法(The grayscale pixel monochrome graphics state record changes in the audio band peak graphical information has been hidden in the audio data, and providing information grayscale graphical methods for taking out)

ISODATA算法,对原本算法进行了简化,计算速度较快()

说明：  对语音信号进行处理，做fft，语谱图，短时fft，并进行对比(The speech signal processing, do fft, spectrogram, short fft, and compare)

三相PWM的svpwm控制SIMULINK程序图(The three-phase PWM control SIMULINK program chart svpwm)

希望学习优化设计原理的同学能够好好利用这个资料啊(Want to learn the principles of optimal design students can take advantage of this information ah)

说明：  基于非负矩阵分解（NMF）的人脸特征提取算法，NMF基本思想是找到一个线性子空间W，使的构成子空间的基本图像的像素点都是正值，而且人脸图像在子空间上的投影系数也是正数(Non-negative Matrix Factorization (NMF) of facial feature extraction algorithm, NMF basic idea is to find a linear sub-space W, so that the composition of sub-space of the basic image pixels are positive, and face image in the sub-space projection coefficient is positive)

批处理for语句从入门到精通，讲述批处理的for语句的机制，目录如下： 一 前言 二 for语句的基本用法 三 for /f 含变量延迟 四 for /r 五 for /d 六 for /l(Batch for statements entry to the master, tells the story of a batch of for statements mechanism, directories are as follows: one preface Two basic uses of the for statement Three for /f with variable delay Four for /r Five for /d Six for /l)

生成导频信号，并利用导频进行信道估计，利用两种方法分别进行信道估计，两种方法并进行了比较。(Generating a pilot signal, and using pilot channel estimation)

一个用于图像去噪的matlab的GUI界面程序实例，可以读入各种图像格式，选择不同去噪方法，产生去噪图像，并在同一界面下同时显示原始图像，加噪图像和去噪图像(one for Image Denoising Matlab GUI interface procedures example, can be read into various image formats, different Denoising, generated image denoising, and the same interface also shows that the original image, increase noise and image denoising images )
