小波分析与应用例程在matlaB中的实现，压缩包里面包含讲义和源代码。(Wavelet analysis routines in MATLAB to achieve compression package which contains the lecture notes and source code.)

最速下降法，优化算法的一种，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点(Steepest descent method, an algorithm with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima)

数字水印matlab程序，只是简单的svd跟最简单的置乱方法Arnold的应用。没有用到小波算法。上传的dwt_svd_GUI.rar是完整的数字水印算法，用的是混沌加密。(Matlab digital watermarking process, with the svd simply the easiest way to Arnold scrambling applications. Wavelet algorithm is not used. From the dwt_svd_GUI.rar is a complete digital watermarking algorithm, using a chaotic encryption.)

Matlab鼠标画图,用pop-up menu选择画图标记,颜色edit记录鼠标坐标 但是功能比较简单，只能画线，不能画矩形、椭圆等 其中一个难点就是：拖动鼠标的过程中如何显示矩形/椭圆的轮廓，并且轮廓跟着鼠标指针移动。 程序的亮点： 1、可选择点、线、矩形、椭圆进行画图； 2、可选择marker、LineTyple进行画图； 3、可选择画图颜色； 4、可实时显示鼠标指针当前坐标； 5、可清除画板； 6、可保存画好的图(bmp、jpg、gif)； 7、操作比较人性化，模仿了windows画板； 8、该程序牵涉的面广，是一个很好的GUI学习资料。 (Matlab mouse drawing, with the pop-up menu select the drawing marks, color edit record mouse coordinates, but relatively simple function, can only draw a line, not drawing rectangles, ellipses, etc. One of the difficulties is this: how the process of dragging the rectangle/oval contours, and outline follow the mouse pointer moves. Program Highlights: 1, select point, line, rectangle, ellipse for drawing 2, optional marker, LineTyple the drawing 3, choose paint colors 4, real-time display the current coordinates of the mouse pointer 5, to clear the drawing board 6, save-drawn map (bmp, jpg, gif) 7, operation more user-friendly, imitating the windows drawing board 8, the program involved a wide range, the GUI is a good learning materials.)

细菌群趋药性算法的程序，网上到处找也没有，我就自己编了个，如果有bug请跟我联系。(The program of Bacterial Colony Chemotaxis algorithm ,I cant find anyone online,so I program it myself, please contact me f there are any bugs.)

语音频率分析使用matlab实现，很经典了呵呵(Voice frequency analysis using matlab implementation, it is the classic of the Hehe)
