  I'm trying to solve an eigenvalue system that can easily
be cast as a generalized eigenvalue system:

                Ax = wBx    (dimension 1332)

EISPACK successfully found the eigenvalue specturm, now I would
like to compare the EISPACK results to a power method.  I would
like to avoid the numerical error introduced by inverting B and
applying it to the LHS.

  Is there a power method for generalized systems?  Or perhaps a
method of refining B-inverse to reduce numerical error?  I've
check Golub & Van Loan and didn't get and helpful directions.

  Any suggestions would be appreciated.
