hankel_inverse


hankel_inverse, a MATLAB code which computes the inverse of a Hankel matrix.

A Hankel matrix is a matrix which is constant along all antidiagonals. A schematic of a 5x5 symmetric Hankel matrix would be:

        a  b  c  d  e
        b  c  d  e  f
        c  d  e  f  g
        d  e  f  g  h
        e  f  g  h  i
