本文件提供了几个数值分析中的Matlab小程序。水平有限，多多海涵。(This document provides several numerical analysis of Matlab small programs. Limited, and many Haihan.)

JEPG2000的开源代码，matlab版本可直接使用。(JEPG2000 open source code, matlab version can be used directly.)

非局部滤波算法的MATLAB代码，适用于图形图像处理(Nonlocal filtering algorithm of MATLAB code, suitable for image processing)

说明：  matlab编写的小波变换程序，有很多实例，是《Matlab小波分析》（张德丰）教程的源程序，很适合学习使用。(matlab wavelet transform procedures for the preparation, there are many examples is &quot Matlab Wavelet Analysis&quot (Zhang Defeng) tutorial source code, it is suitable for learning to use.)

THE ALGORITH OF RGB TO HSV USE MATLAB

说明：  此程序给出由三个不同频率的正弦所组成信号的联合时－频分布。该图是三维图形的二维投影，在该图中，一个轴是时间，一个轴是频率。由该图可清楚地看出信号的时间－频率关系。(This program shows three different frequency sinusoidal signal composed of joint time- frequency distribution. The plan is two-dimensional projection three-dimensional graphics in the figure, one axis is time, an axis is frequency. By the diagram is clear that the signal of the time- frequency relation.)

说明：  matlab与科学计算的教程编写的课堂课件(MATLAB and science calculational)
