## "Simplifying" matrices ?

 Hi again, the previous answers were great. I was able to do what was planned. Now, I would like to do the following to a matrix: || year | event | team | total || where I can have multiple "event" per "team", but each "team" only has a "year" and a "total". Thus, this table has multiple lines for the same "team" where only the "event" changes. Considering this, how can I output this: || year | team | total || where each "team" occurs only once, and the "event" was discarded. Hope I made myself clear. Thanks in advance. This is a great mailing list.
