一种通用的稀疏编码方法，sparse coding，在图像去噪，目标识别等方面有着广泛的应用。(A generic sparse coding, sparse coding, in image denoising, object recognition have a wide range of applications.)

说明：  光学工程类的Matlab模拟程序，一个是透镜的成像原理模拟，一个是平板成像(Optical engineering classes Matlab simulation program, one lens of the imaging principle simulation, a flat-panel imaging)

通过用类似于阶跃折射率型光纤的理论，计算光子晶体光纤的基模模式折射率和色散。 (By analogy with the theory of step-index fibers, the effective index of the fundamental mode and the dispersion of PCF can be calculated. )

a.阅读的图像img_1.tif，img_2.png的文件夹中，并 他们展示于一体，这两个数字分别。 （参考函数：imread, imshow, figure, subplot） b.在matlab，观察从工作区中的图像信息面板 c.分别使用size, imfinfo,whos等功能获得的图像信息 d.添加标题的图像。 （参考函数：title） Ë 。下面的代码实现的M文件编辑器 f=imread(‘img_1.tif’) imshow(f) set(figure(1), NumberTitle , off , Name , my first image’) 观察结果，并确定的功set() f。保存img_1.tif目录“D： imagetest”。如果该文件夹不 存在，请首先创建这个新的文件夹。 （参考函数：imwrite） (a. Read the images img_1.tif, img_2.png given in the folder, and show them in one and two figures respectively. (referenced function: imread, imshow, figure, subplot) b. In matlab, observe the images information from the workspace Panel c. Use size, imfinfo,whos,etc functions to obtain image information respectively. d. Add title to the images. (referenced function: title) e. Implement the following codes in the M-file Editor f=imread(‘img_1.tif’) imshow(f) set(figure(1), NumberTitle , off , Name , my first image’) observe the result, and determine the function of set() f. Save img_1.tif to the directory “d:imagetest”. If the folder does not exist, please create this new folder first. (referenced function: imwrite))

说明：  Parzen窗拟合标准正态分布（Matlab实现）(Parzen window fitting the standard normal distribution (Matlab implementation))

Matlab中的电弧电路编程，45KB，个人觉得还是很有用的。(Arc circuit in Matlab programming, 45KB, personally think it is very useful.)

语音信号处理中低通滤波器的设计程序，实现效果比较好。(Speech signal processing)

基于matlab的风机信号处理，包括时域频域各种分析方法(Fan-based signal processing matlab, including a variety of analytical methods and frequency domain)
