Automatic method in Eigenvalues

With Mathematica it is easy to obtain the Eigenvalues of a (large)
matrix (Function Eigenvalues). Currently I am writing a paper and I
would like to know which algorithm is used by Mathematica for a n x n
matrix (n >= 5). The eigenvalues cannot be determined analytical, thus I
am interested in which numerical method Mathematica uses. Using Options
I can only find that the Method is Automatic (which does not help).

Kind regards,
