中文说明：
基于MATLAB软件，使用者在交互界面GUI上输入入射介质、反射介质的折射系数n1、n2，可算得不同入射角条件下线偏光/自然光的菲涅尔透反射系数及透反射比。
English Description：
Based on MATLAB software, the user can input the refractive coefficients N1 and N2 of incident medium and reflection medium on the GUI of interactive interface to calculate the Fresnel transmission and reflection coefficient and transmission and reflection ratio of linear polarized light / natural light under different incident angles.
