G. Heinig et F. Hellinger, ON THE BEZOUTIAN STRUCTURE OF THE MOORE-PENROSE INVERSES OF HANKEL-MATRICES, SIAM journal on matrix analysis and applications, 14(3), 1993, pp. 629-645
It is shown that the Moore-Penrose inverses of Hankel matrices are gen
eralized Bezoutians. This result generalizes the well-known fact that
Hankel matrix inverses are (classical) Bezoutians.
