The question of inverting a matrix of polynomials modulo a zero dimensional 
regular chain (a triangular set encoding a finite number of solutions)
is considered. We show that resurrecting the well-known Leverrier's algorithm
yields new results for this question. Experimental and complexity results are given.

This is joint work with Marc Moreno Maza.
