【Matlab界面GUI添加背景图片】：好像桌面背景一样，添加自己想要的背景图片，这里面有个技术，可以让背景不影响GUI界面的文字，edit、text。具体代码下载了解一下吧，平时工作总结的方法。(Matlab interface [GUI] Add a background image: It seems as desktop background, you want to add your own background image, and there are a technology that allows the background without affecting the GUI interface text, edit, text. Specific code to download understand it, the usual method of summing up the work.)

按键式电话如下图所示，当按下某一个键时会产生如图所示的相应的频率模拟信号，并通过对该信号频率的检测，识别出对应的按键。试通过编写一个数字信号分析程序，模拟完成上面的功能。(Touch-tone phone as shown below, when pressing a key will be generated as shown in the corresponding frequency analog signals and, through detection of the signal frequency to identify the corresponding button. Test through the preparation of a digital signal analysis program to simulate the function of the completion of the above.)
