jpeg compression , use DCT, Zigzag, Quantization,IDCT, InvZigzag, huffman to do the compression with matlab

matlab入门到提高，全面讲解了matlab的使用(Introduction to matlab improved overall on the use of the matlab)

说明：  读取RGB24彩色图像的dat文件，没帧图片大小为320*240，然后对图片进行直方图均衡，一种是调用matlab接口，一种是自己写的，读取C语言处理的dat文件，都显示出来进行对比(Read the RGB24 color image dat file, no frame picture size is 320* 240, and then the image histogram equalization, a call matlab interface, one is to write your own, read dat files of the C language processing, displayed for comparison)

说明：  DSP入门：在MATLAB中应用傅里叶变换分析信号频谱(DSP basis: Implement fourier transform to analysis signals spectrum with MATLAB)

Decision region vector For the decision region Number of bins for the data Percentage of incorrectly assigned samples at a nod Unknown command option This function recieves a parameter vector and returns it s components The parameter vector is completely numeric. This is much simpler Percentage of incorrectly assigned samples at a node

说明：  实现特征波长的提取，连续投影算法可以实现特征光谱信息，结合PCA实现样品分类(Realize the extraction of characteristic wavelength)

简介：采用matlab完成了SAAB3010红外遥控板的编码发射显示，通过GUI界面可以清楚了解其发射编码格式，有助于红外遥控编解码的学习。 关键词：matlab SAA3010 红外遥控 GUI(Description: The complete SAAB3010 matlab coding infrared remote control panel emission displays, through the GUI interface can be a clear understanding of its launch encoding, decoding infrared remote control help learning. Keywords: matlab SAA3010 Infrared Remote Control GUI)

阶跃型折射率光纤中的模式容量和光功率分布，单模光纤的特征方程及其MATLAB数值求解，多模光纤的特征方程及其MATLAB数值求解(Step-index fiber modes capacity and optical power distribution, single-mode fiber and MATLAB numerical solution of the characteristic equation, multimode fiber and its MATLAB numerical solution of the characteristic equation)

该程序专门用于计算，金融证券估值计算股票期权的二项树过程。(The code can be used to plot generated binomial processes of stocks and options.)

This function computes the LP guided modes of a step-index optical fiber using Matlab s "fzero" function available in the Matlab s Symbolic Toolbox. The "fzero" function uses Brent s method to find the root of a continuous function of one variable given an initial guess value.
