Dear experts,

The current iterative algorithm for signm can be improved.
The theory is given in a recent paper by Bai et. al.

The spectral decomposition of nonsymmetric matrices
on distributed memory parallel computers,
SIAM J. Sci. Comput. Vol. 18 (5) pp. 1446-1461

Any cooments ?

                       Nils
