升采样，用于分析ISAR/SAR成像算法成像质量，分析点目标距离向/方位向剖面切片，观察主瓣与旁瓣，也可以用于定性分析不同算法对同一目标点成像质量的好坏。也可用于分析峰值旁瓣比与积分旁瓣比等。(Liter sample for analysis ISAR/SAR imaging algorithm image quality, the analysis points to the target distance/azimuth cross-sectional slices, observe the main lobe and side lobes to be good or bad for the qualitative analysis of different algorithms on the same target image quality. It can also be used to analyze the ratio of peak sidelobe sidelobe integral ratio.)

说明：  这是二战时期著名的，独领一时风骚的密码机Enigma的源代码，它真实的再现了Enigma的工作原理和真实原貌，希望有兴趣的朋友共同参详(This is the famous World War II, was the sole lead of 1:00 coquettish Enigma cipher machine source code, it is a true reproduction of the working principle of the Enigma and true original, want to have a friend interested in the common parameters are set)

工具箱中包含台湾清华大学张星智教授的三个语音信号处理工具箱，还有常用的voicbox以及一份详细讲解如何添加工具箱的word教程。(Toolbox contains the word tutorial Tsinghua University of Professor Zhang Xingzhi three voice signal processing toolbox used voicbox explain in detail how to add a toolbox.)

一般情况下，ellipse函数只能实现尺度较小的椭圆模拟，次程序实现长短轴较大且椭圆中心在任意象限情况下的椭圆模拟函数(for the semi-major and semi-minor ellipse simulation)
