PCA

This is for testing a matlab program.

使用MATLAB制作gui，有代码举例，有ppt说明(Produced using MATLAB gui, there is the code example, there ppt shows)

本程序已被本人整理到WORD文档中，编程语言为MATLAB，程序中首先利用非递归法产生滤波器系数，生成相关高斯杂波，直接对杂波信号作FFT变换，结果取模平方后除以长度N,即可得到杂波的功率谱，设计参数皆在文档中表明。此程序已经验证是正确可执行的，并能生成图形，值得下载！( This program has been organized into WORD document I, the programming language MATLAB, the program produced the first method using non-recursive filter coefficients to generate the relevant Gaussian clutter, clutter signals directly to FFT transform, the result after the square modulus divided by the length of the N, can be obtained the power spectrum of clutter, design parameters are indicated in the document. This procedure has been verified is correct executable, and can generate the graph, it is worth to download!)

Inputs: Two square matrices a and b and a natural number nk

实现了数字信号处理在双音多频拨号系统中的应用，并用MATLAB实现。(Realization of the digital signal processing in a dual tone multi-frequency dialing system, and use MATLAB implementation.)

this code generate the histogram of a picture and normalize it .

多分类相关向量机程序，有运行demo，运行速度快，无bug(More relevance vector machine classification procedures, run demo)

this program is designed for solving the two dimensional photonic structure

说明：  利用小波变换实现对故障信号的特征提取 构造特征向量(Wavelet transform feature extraction of fault signals structural feature vector)

本文是个人整理的，对S函数的原理做了基本介绍，然后对S函数的面板进行了详细的注解，算是加入了自己理解的翻译(This article is the personal finishing basic principle function of S, then the S-function panel detailed annotations, regarded as adding their own understanding of the translation)
