Comparison of eigenvalues. Distribution of eigenvalues of four real datasets used in this work ((a) PBMCs, (b) Pancreas, (c) BrainSpincalCord, and (d) Brain). The x-axis means the principal components of each principal component analysis (PCA) implementation, and the y-axis means the corresponding eigenvalues
