scipy.linalg._flapack:dlangb

Parameters

norm : str

'M' for the largest absolute value, '1' or 'O' for the 1-norm, 'I' for the infinity norm, 'F' or 'E' for the Frobenius norm. Lower case is accepted. Note that 'M' is not a consistent matrix norm.

kl : int

Number of subdiagonals.

ku : int

Number of superdiagonals.

ab : ndarray

Band storage of shape (kl + ku + 1, n): a[i, j] is held at ab[ku + i - j, j].

ldab : int, optional

Leading dimension of ab, at least kl + ku + 1, which is also the default.
