4）读取音乐信号romanza_pe.wav, 截取其前10s信号，选择适当的窗口类型和窗口宽度，显示其短时傅立叶频谱，以便能更清晰地看清谱线。说明信号频谱特点。 5）令D=5下采样音乐信号，播放其声音并显示其短时傅立叶频谱。描述并解释你所听到的声音和观察到的频谱之间的关系() Read the music signal romanza_pe.wav, intercept its first 10 s signal, select the appropriate window type and window width, display its short-time Fourier spectrum, so as to be able to see the spectrum lines more clearly. The characteristics of signal spectrum are explained. 5) let D=5 sample the music signal, play its voice and display its short-time Fu Liye spectrum. Describe and explain the relationship between the voice you hear and the observed spectrum.)

MK ( Mannkendall)检验和突变点检验R程序(R program for MK (Mannkendall) analysis)

模拟退火算法实现旅行商问题，输入城市数目以及城市距离的邻接矩阵，程序输出最短回路序列以及对应的距离。(Simulated annealing algorithm realizes the traveling salesman problem, inputs the adjacency matrix of the number of cities and the distance between cities, and outputs the shortest loop sequence and the corresponding distance.)

一个js树控菜单 展开的树形菜单，js无限级树形菜单代码三种风格，看一下效果图便明白每一款风格的样式，觉得都是挺漂亮的，其实这是一款树菜菜单插件，名字叫做："CNL Tree Menu"，无限级树形，具有以下特点：浏览器兼容好，支持：IE5.0+, FF1.06+, Opera8.5+ …… 　　HTML,CSS,JavaScript代码相互分离(即数据，风格，脚本三者分离)，可应用于多种场合，易于维护修改；更换树形图标，只需要修改CSS文件. 　　通过W3C校验(XHtml1-Strict,CSS1.0).

matlab code for dmodce, ddemodce which is inbuilt function in old version matlab

Catia Script generated from VB. very usefull for catia users. this macro automated the process of activating part bodies in the product automatically.

将各个项目子目录拷贝到硬盘上,然后可以用Visual Basic打开程序(Copies all subdirectories to the hard disk, and then can open the program with Visual Basic)

本工程用于LPC1788外加AT070TN83，外接SDRAM作显存，ucGui移植完成(其实也不是移植，也就修改了几个地方，第一次用还是有点麻烦的，以前没用过ucGui) 本文件夹中另有一个GuiLib这个工程是用于生成ucGui.lib库文件，如果直接将ucGui源文件加入到你的工程文件中那个编译时间真让人受不了，ucGui的编译差不多要2分钟，如果要修改ucGui的东西，请修改后再重新编译一下。 显例程显示的是dialog_all.c的对话框，网上下载的例子(LPC1788 ucGui)
