电流环仿真，用MATLAB，采用Simulink(Current loop simulation, using MATLAB, using Simulink)

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.

说明：  matlab计算信号近似熵，具体参数文件中有说明(Matlab calculates the approximate entropy of the signal, which is explained in the specific parameter file)

将原图像用bior四层分解，之后弱化低频分量，重构原图，以得到细节。(use wavelet function(bior) to enhance the detail of the image,then reconstuct)

图形的透视演示,两个圆，外面一个镂空，投射里面一个圆。(Presentation graphics perspective, the two round, outside a stencil, projection inside a circle.)
