MATLAB

各种matlab代码，实现各种功能，供查阅者参考，熟悉matlab软件的使用(x=linspace(0,1,21) y=linspace(0,1,21) [X,Y]=meshgrid(x,y) z=(X.*Y)./(X+Y) meshc(X,Y,z) )

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.)

运用matlab实现数字滤波器，主要是采用的频率采样法(Realize the use of matlab digital filter is mainly used in the frequency sampling method)

说明：  这是关于matlab图行处理方面的源代码，说明matlab有强大的图形处理功能(This is a matlab figure on the source code line treatment, indicating that matlab has powerful graphics capabilities)

利用DFT法求周期信号的功率谱,实现离散傅立叶变换DFT,最后分析得到频谱幅度.(DFT method using the power spectrum of periodic signals seeking to achieve the Discrete Fourier Transform DFT, the final analysis, amplitude spectrum obtained)

利用matlab编写的kalman的实际应用例子程序，对学习kalman自适应滤波可以学习一下(using Matlab prepared by the Arch example of the practical application procedures Adaptive learning Kalman filter can learn from this)

wlan物理层仿真文件的说明，便于读者理解上手(Description wlan physical layer simulation files, easier to understand to get started)

matlab program is present in the file

matlab图像处理很好的学习参考资料，讲解很详细(matlab image processing good learning reference materials, explaining in great detail)

matlab的两个小球碰撞的模拟程序，很简单的。平时没事瞎编的。(Two small ball collision matlab simulation program, very simple. Usually nothing fabricated.)
