本代码的依据是光的折射定律，展示了光的折射路径，，包括光从光疏介质到光密介质，以及光密介质到光疏介质的折射，并且将不同入射角的情况展示在一张图像中，可以更直观的观察折射情况。

太阳黑子是人类长久以来感兴趣的问题。此处运用matlab代码对太阳黑子的记录的数据进行处理，希望能提供帮助( Using archival records,astronomers have applied Wolfer s rule to determine sunspot activity back to the year 1700. Today the sunspot index is measured by many astronomers and the worldwide distribution of the data is coordinated by the Solar Influences Data Center at the Royal Observatory of Belgium. The text file sunspot.dat in the matlab/demos directory has two columns of numbers. The first column is the years from 1700 to 1987 and the second column is the average Wolfer sunspot number for each year.)
