Exact Inverse of a Hilbert Matrix
Syntax invhilb(n)
See Also hilb

Description
Returns an n x n double-precision matrix containing the inverse of the n x n Hilbert matrix . This is slower but more accurate than inv(hilb(n)).

Example
If you enter
     invhilb(2)
 O-Matrix will reply
     {
     [ 4 , -6 ]
     [ -6 , 12 ]
     }
 If you enter
     invhilb(2) * hilb(2)
 O-Matrix will reply
     {
     [ 1 , 0 ]
     [ 0 , 1 ]
     }
