“…The spectral differences re ect the differences in the composition of Chinese Herbal Medicines samples, which can be visually expressed by the degree of overlap of spectral lines in the overlapping spectral graphs. These intuitive differences can be quantitatively expressed by the Euclidean distance between spectral vectors, the cosine of the included angle, and the Pearson linear correlation coe cient [30,37]. In this paper, the Pearson linear correlation coe cient (Eq.…”
