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.)

有用的matlab数据，大家看一下，或许对你有帮助。(Matlab useful data, we look at, perhaps to help you.)

it s about locating TDOA algorithm

It is a matlab sourcecodes for the calculation of refrective index of AlGaAs alloy. I think it is useful for the guys who need the accurate value of the refrective index. It can be expanded to the other semiconductor alloy if you have the related parameters.
