| L[1] contains the (n+1) coefficients of the characteristic
polynomial X of A, i.e.
X = L[1][1]+..+L[1][k]*t^(k-1)+..+(L[1][n+1])*t^n
L[2] contains the n (nxn)-matrices Hk which are the coefficients of
the busadjoint bA = adjoint(E*t-A) of A, i.e.
bA = (Hn-1)*t^(n-1)+...+Hk*t^k+...+H0, ( Hk=L[2][k+1] )
