From: Enhancing spectral analysis in nonlinear dynamics with pseudoeigenfunctions from continuous spectra

Spectral embedding of ResDMD’s pseudoeigenfunctions of principal angle (Left), DMD’s eigenfunctions of principal angle (Middle), mpEDMD’s eigenfunctions of principal angle (Right). We use fuzzy C-means to perform soft clustering, with the three clusters color-coded according to their membership degree.
