利用MATLAB写的蹦球游戏，希望大家在学习的同时可以放松下，顺便学学matlab(The use of MATLAB in bouncing ball Writing Game, I hope everyone in the study can relax at the same time, the study incidentally learn matlab)

This code demomstrates an improved algorithm based on the local binary fitting (LBF) model in Chunming Li et al s paper: "Minimization of Region-Scalable Fitting Energy for Image Segmentation", IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008. Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows. Run the Demos in the M-files for several test images. Once an image comes out, click the mouse to generate a polygon as the initial contour: left click to get a number of points, then right click to get the end point. The number of iterations may need to be increased if the initial contour is too far away from the desired object boundary.

图像分割图像分割基于MATLAB像素邻域自适应阀值分割图像 适合用本程序处理用MATLAB的图像处理的任务(Image segmentation image segmentation MATLAB adaptive threshold image segmentation of neighborhood pixels for this procedure for image processing tasks based on MATLAB)

说明：  读取文件夹中的音乐波形，进行FFT分析，显示出其时域波形和频谱波形(Read the music waveform in the folder and analyze it by FFT)

RHis mfiles is for optimlal conr=trol ddassdddd

本例很好的解释了FFT变换的功能，例程简单易懂，能够很好的用于理解FFT，观察信号频谱。(In this case a good explanation of the function of FFT transform routines easy to understand, can be very good for understanding the FFT, observe the signal spectrum.)

用matlab软件求解复合材料结构设计中层合板刚度系数计算程序(A program for calculating stiffness coefficient of composite laminates based on composite structure design)

输出量通过回路使得占空比D增加或减少，以控制电压的输出或减少，从而达到最大功率点(Output circuit by which the duty ratio D is increased or decreased to reduce the output or control voltage to achieve maximum power point)

此函数用于求得多重小波变换后的低频小波系数，在matlab自带的函数基础上改的。(this function to obtain multiple wavelet transform the low-frequency wavelet coefficients, In Matlab built-in function on the basis of reform.)

说明：  该程序介绍Matlab时频分析技术及其应用，利用该程序可以分析周期信息(This program is used to get the frequence. )
