Hi

i am trying to perform diagonalization of a 3x3 matrix, of the form:

[ e1, V, 0 ]
H := [ V, e2, V ] [ , V, e3 ]

which gives rise to a multivariate characteristic polynomial.

Since that seems to be a complicated task, that symbolic software cannot solve (i have tried with
Maxima and Mupad) i would be grateful if you could point me some references (preferably on line or
books) where to learn about approximated algebraic methods to get the eigevectors of H.

Thank you
