Subject Re: [math] Matrix subMatrix and mean methods
Date Tue, 05 Oct 2004 19:25:03 GMT
Hello Wolfgang,

You jogged my memory concerning our discussion on this subject some time 
ago. You had given me a contact (James Casey) at CERN to discuss this 
subject further and I think the subject slipped off the radar at that 
point. Here was that old thread. I've cc'd him on this message to 
re-initialize discussion.
