Useful functions for LinearOperators

Functions

eigendecomposition(A, **kwargs)
A wrapper to arpack eigen_symmetric which output an approximation of the A input matrix, as a LinearOperator storing eigenvalues and eigenvectors.

source code

cond(A, k=2, kl=None, ks=None, symmetric=True, M=None, maxiter=None, tol=1e-06, verbose=False, prune_zeros=False, loweig=None)

eigendecomposition(A, **kwargs)

source code

A wrapper to arpack eigen_symmetric which output an approximation of the A input matrix, as a LinearOperator storing eigenvalues and eigenvectors.

It passes its arguments arguments as arpack.eigsh but forces return_eigenvectors to True.
