> In SingularValueDecompositionImpl, the condition number is given as the ratio
> of the largest singular value to the smallest singular value. While this is
> the correct calculation, because of concerns over rank deficiency,
> researchers have traditionally used the inverse of the condition number as a
> more stable indicator of rank deficiency.
