Hi all,
Could anyone please refer to me to a paper or other resource that explains
in detail (specifically technical) on how to preform g_lie. I know the
matter has been brought up here quit often lately but looking through the
mailing list archives and reference papaers (Aquist et al. and similar) tend
to focus on the theory rather than practice.
Thanks in advance,
Gideon
