** Hilbert matrix. **

** HILB(N) is the N by N matrix with elements 1/(i+j-1), **

** which is a famous example of a badly conditioned matrix. **

** See INVHILB for the exact inverse. **

** This is also a good example of efficient MATLAB programming **

** style where conventional FOR or DO loops are replaced by **

** vectorized statements. This approach is faster, but uses **

** more storage. **
