今日对光谱数据预处理中的MSC（多元散射校正）和SG（0阶、高阶）平滑进行了学习，参考书目是李志刚老师著的《光谱数据处理与定量分析技术》（原理介绍较为详细）并结合CSDN和联合开发网上下载的代码进行了简单的matlab编程。代码稍后上传，介绍详细，感兴趣的可以去看看。(Today, MSC (Multiple Scattering Correction) and SG (0th order, high order) smoothing in spectral data preprocessing are studied. The bibliography is "Spectrum Data Processing and Quantitative Analysis Technology" by Li Zhigang (more on the principle) . And combined with CSDN and joint development of the code downloaded online to carry out a simple matlab programming. The code is uploaded , and the details are detailed. If you are interested, you can check it out.)
