 r"""Compute reciprocal condition number of a matrix. Args: lu_mat (numpy.ndarray):
 A 2D array of a matrix :math:`A` that has been LU-factored, with the non-diagonal part of :math:`L` stored in the strictly lower triangle and :math:`U` stored in the upper triangle. one_norm (float):
 The 1-norm of the original matrix :math:`A`. Returns: float: The reciprocal condition number of :math:`A`. Raises: OSError: If SciPy is not installed. RuntimeError: If the reciprocal 1-norm condition number could not be computed. """
