- scipy.linalg.expm_cond(A, check_finite=True)¶
Relative condition number of the matrix exponential in the Frobenius norm.
A : 2d array_like
Square input matrix with shape (N, N).
check_finite : bool, optional
Whether to check that the input matrix contains only finite numbers. Disabling may give a performance gain, but may result in problems (crashes, non-termination) if the inputs do contain infinities or NaNs.
kappa : float
The relative condition number of the matrix exponential in the Frobenius norm
A faster estimate for the condition number in the 1-norm has been published but is not yet implemented in scipy.
New in version 0.14.0.
