模拟退化算法在C环境下的实现，以及在Matlab中对其进行调用。(Simulation of the degradation of algorithm in C environment to achieve, as well as in Matlab in their call.)

This is to plot frequency spectrum using Welch method.

本程序基于Matlab，可以对特定波长光线在透镜系统中进行光线追迹。可以生成任意方向平行光，点光源任意角度光线，并对全反射，光线射出系统等特殊情况用红色标出。透镜数任意，透镜参数可设。(The program is based on Matlab, with a specific wavelength of light in the lens system for ray tracing. Parallel light can be generated in any direction, at any angle point source of light, and the reflection of light injection system and other special circumstances marked in red. Any number of lenses, lens parameters can be set.)
