Mean value(centroid) of a collection of vectors

[daveronan]

If I have a collection of vectors in very high euclidean space(n=72). How do I find the mean value of all the vectors? Maybe I'm using the incorrect terminology. Maybe I want to find the centroid of where all these vectors are?? I'm working on a machine learning algorithm. Any help would be greatly appreciated.

I'm essentially looking a for a vector that would give a good indication of where all the other vectors are clustered together. I hope to add new vectors to this group based on cosine similarity of the new vector and the mean value.

It's ok, I think I've found what I'm looking for. http://www.utdallas.edu/~herve/abdi-WireCS-Centroid-2009.pdf
