描述ＥＤＧＥ系统接收机结构，包括prefilter和均衡器(Description EDGE receiver structure, including the prefilter and the equalizer)

数字图像滤波的程序，包括散斑噪声的生成，中值，均值，Lee，Kuan滤波算法的实现，还计算了三个指标：峰值信噪比，等效视数，散斑指数。(Digital image filtering process, including the generation of speckle noise, median, mean, Lee, Kuan filtering algorithm, also calculated three indicators: the peak signal to noise ratio, equivalent number, speckle index.)

Sort back sorted data to initial state

这可是我两年前用matlab写的第一个函数，算是处女作。 这个例子涉及三角函数的系数变换及其极坐标系绘图，以及界面和控件的颜色修改。(But I used it two years ago to write the first matlab function can be regarded as a debut. This example involves the coefficient of trigonometric function transform and its polar coordinates drawings, as well as the interface and control color modify.)

Matlab具有强大的数值计算和分析等能力,而C/C++是目前最为流行的高级程序设计语言,两者互补结合的混合编程在科学研究和工程实践中具有非常重要的意义。因此,从Matlab调用C/C++代码及C/C++调用m文件两方面,深入地研究了它们之间混合编程的原理和实现机制,并且给出了具体条件下的混合编程方法和步骤。实例表明,提出的Matlab与C/C++混合编程方法是简洁、有效的。(Matlab has strong ability of numerical value calculation and analysis,whereas C/C++ is one of the most popular programming languages.And the mixed programming of Matlab and C/C++ is significant in scientific research and engineering applications.Therefore,the mechanism of Matlab inducing C/C++ codes and C/C++ calling m file are proposed separately.The mixed programming methods and approaches in different conditions are also presented.At last,the validity of the mixed programming between Matlab and C/C++ is ...)
