    Bug report
    The text definition of the L2 norm is incorrect. The calculated result is correct though.

    Is says it''s the maximum eigenvalue of A, that is lambda_max(A).
    Instead it should say that it''s the largest spectral radius, that is sigma_max(A).
    Equivalently that''s the largest eigenvalue of A^T.A (or A^* A for complex matrices).
