- scipy.linalg.interpolative.estimate_spectral_norm(A, its=20)[source]¶
Estimate spectral norm of a matrix by the randomized power method.
Parameters: A : scipy.sparse.linalg.LinearOperator
Matrix given as a scipy.sparse.linalg.LinearOperator with the matvec and rmatvec methods (to apply the matrix and its adjoint).
its : int, optional
Number of power method iterations.
Returns: float
Spectral norm estimate.
