# scipy.linalg.interpolative.estimate_spectral_norm

scipy.linalg.interpolative.estimate_spectral_norm(A, its=20)

  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
