[SciPy-user] scipy.sparse.linalg.eigen

Hi all,

I am interested in the eigenvalues of a product of 
matrices:

M_m M_{m-1} \cdots M_1 x_0 = \lambda x_0   (1)

The problem can be rewritten as a generalized eigenvalue
problem

A z = \lambda B z,    (2)

where B is singular.
I am only interested in the f i n i t e eigenvalues of 
(2).
So far I have solved the problem by scipy.linalg.eigvals.

Is it possible to compute these eigenvalues with
scipy.sparse.linalg.eigen ?

Nils
