On the wikipedia page, they state that the condition number grows as. O ( ( 1 + 2) 4 n / n. I think the corresponding reference for this statement is the paper "The Condition Number of the Finite Segment of the Hilbert Matrix", by John Todd ...

WebHilbert matrices are ill-conditioned, meaning that they have large condition numbers indicating that such matrices are nearly singular. Note that computing condition numbers is also prone to numeric errors. cond (H) ans = 5.1944e+19 Therefore, inverting Hilbert matrices is numerically unstable.
