numpy.linalg.eigh¶ numpy.linalg.eigh(a, UPLO='L') [source] ¶ Return the eigenvalues and eigenvectors of a Hermitian or 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).

I have a problem diagonalizing a 4200 by 4200 symmetric real matrix, as numpy.linalg.eigh raises numpy.linalg.linalg.LinAlgError: Eigenvalues did not converge. On the other hand scipy.linalg.eigh works with the same matrix.

cupy.linalg.eigh¶ cupy.linalg.eigh (a, UPLO = 'L') [source] ¶ Eigenvalues and eigenvectors of a symmetric matrix. This method calculates eigenvalues and eigenvectors of a given symmetric matrix. Parameters. a (cupy.ndarray) – A symmetric 2-D square matrix (M, M) or a batch of symmetric 2-D square matrices (, M, M). UPLO – Select from 🐛 Bug I am trying to understand why am I getting different eigenvalues between using numpy.linalg.eigh() and torch.symeig(). To Reproduce An example is as below. Code: import numpy as np import torch arr_symmetric = np.array([[1.,2,3], [ numpy.linalg.eigh¶ numpy.linalg.eigh(a, UPLO='L') [source] ¶ Return the eigenvalues and eigenvectors of a Hermitian or symmetric matrix.

Aliases: tf.linalg.eigh; tf.self_adjoint_eig; tf.self_adjoint_eig( tensor, name=None ) Defined in tensorflow/python/ops/linalg_ops.py.. See the guide: Math > Matrix

Solves tensor equations denoted by ax = b.. cupy.linalg.lstsq. Return the least-squares solution to a linear matrix equation.

In a Python 3 application I'm using NumPy to calculate eigenvalues and eigenvectors of a symmetric real matrix. Here's my demo code: import numpy as np a = np.random.rand(3,3) # generate a random array shaped (3,3) a = (a + a.T)/2 # a becomes a random simmetric matrix evalues1, evectors1 = np.linalg.eig(a) evalues2, evectors2 = np.linalg.eigh(a)

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).

The following are 30 code examples for showing how to use numpy.linalg.eigh().These examples are extracted from open source projects.
