摘　　要：在分析MATLAB颜色显示方法的基础上,通过构建插值函数建立了可见光波长与MATLAB色谱矩阵参数的映射关系.依据这一映射关系,把按照真实实验参数计算获得的杨氏干涉实验干涉图样的强度分布,变成了用于干涉图样显示的色谱矩阵,从而实现了单色光杨氏干涉实验的计算机写真.这种方法可广泛用于与可见光有关的物理现象的讨论与分析.Based on color displaying method on screen of MATLAB, the mapping relationship between visible wavelength and data in colormap matrix of MATLAB was erected by building up interpolating function. According to the mapping relationship, the intensity distribution of interference patterns of Young＇s experiment, calculated by inputting actual experimental data, turns to colormap matrix of interference pattern. In result, describing interference pattern of monochromatic Young＇s experiment as it is with computer is realized. The proposed method in this article can be used widely on discussing the physical phenomena related to visible light.
