Webhilb. Hilbert matrix. Syntax. H = hilb(n) Description. H = hilb(n) returns the Hilbert matrix of order n. Definition. The Hilbert matrix is a notable example of a poorly conditioned matrix .The elements of the Hilbert matrices are . 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.
