numerical eigenvectors?



Is there a way to get reliable numerical estimates of eigenvectors and 
eigenvalues from maxima? I have a jacobian of a system of ODEs that I'd 
like to analyze at equilibria. symbolically it's too complicated, but if 
I plug in the equilibrium numerical values and try to evaluate the 
eigenvectors maxima doesn't like it either.

octave gives me good estimates instantaneously. apparently they use some 
kind of matrix factorization which I don't know if we have available in 
maxima?

thanks,
Dan
