Also D contains eigenvalues only, hence it has to be shaped into matrix form. Hence the reconstruction can be formed with import numpy as np U, D, V = np.linalg.svd (A) A_reconstructed = U @ np.diag (D) @ V
Interestingly, SVD has been used to improve gravitational waveform modeling by the ground-based gravitational-wave interferometer aLIGO. SVD can help to increase the accuracy and speed of waveform generation to support gravitational-waves searches and update two different waveform models.
