这个例子阐明了发生在时变系统中的频谱扩展，系统的带通输入时在某个频率上的音频信号(This example illustrates the system occurred in the time-varying spectrum expansion of the system' s band-pass input on a frequency of audio signal)

LED 二次光学设计中的透镜设计，根据非成像光学原理，利用matlab计算生成二维点坐标，可导入3维建模软件，生产模型。代码经过测试，可成功完成计算。大家可以参考一下。(LED optical design, lens design, according to the non-imaging optics principle, the use of matlab calculation to generate two-dimensional coordinates can import 3-D modeling software, the production model. The code has been tested and successfully completed the calculation. We can refer to.)
