numpy.linalg.eigh Return the eigenvalues and eigenvectors of a complex Hermitian (conjugate symmetric) or a real symmetric matrix. Returns two objects, a 1-D array containing the eigenvalues of a , and a 2-D square array or matrix (depending on the input type) of the corresponding eigenvectors (in columns).

Accounting; CRM; Business Intelligence There is another method such as linalg.eigh which is used to decompose Hermitian matrices which is nothing but a complex square matrix that is equal to its own conjugate transpose. The linalg.eigh method is considered to be numerically more stable approach to working with symmetric matrices such as the covariance matrix.

scipy.linalg.eigh and numpy.linalg.eigh calculates different eigenvalues for a symmetric matrix ! Thank you for providing the script and the dataset. Please provide output of conda list --explicit , as well as your processor type.

Return the least-squares solution to a linear matrix equation. Summary: This PR adds `torch.linalg.eigh`, and `torch.linalg.eigvalsh` for NumPy compatibility. The current `torch.symeig` uses (on CPU) a different LAPACK routine than NumPy (`syev` vs `syevd`).
