说明：  MATLAB 编写的用matlab 来实现的pde图像增强方法，如果不对的地方，请各位指出。(This is an enhance image example to use pde ways,if there is some problems ,please tell me )

自己编写的用谱相减，最小均方和维纳滤波实现语音增强的matlab文件(themselves with the preparation of spectral subtraction, the minimum mean square Wiener filtering and enhanced voice document Matlab)

MATLAB 的简单程序，初学MATLAB者可以看看，对学习它的使用方法很有效(MATLAB a simple procedure, MATLAB beginner can look at learning to use it very effective)

直接序列扩频通信系统仿真程序，使用matlab语言设计的程序。(direct sequence spread spectrum communication system simulation, the use of Matlab language design process.)

matlab的简明实例教程，可以自己研究一下 还不错的教程(concise instance of matlab tutorials, you can look pretty good your tutorials)

使用Matlab实现双极性不归零码，画出波形并给出功率谱。(use Matlab bipolar not NRZ, paint and wave power spectrum is given.)

Differential equations (in this case is the ordinary differential equation) means containing one, two, and even high-differential equations unknowns. Is to solve the partial differential equations, mathematical equations based. There are many special functions, are not drawn to a number of functions or functions beyond the type of analytical solution of differential equations which define them. These special functions are important because they describe the nature of certain phenomena, for example, electronic activities, drum skin vibrations, pendulum swing, and so on.
