Kick ass Matt

great to hear form you.

I believe that the linear Algebra Class in Numpy can get that done as
long as you feed in the right matrix.
I guess I don;t know how to get a covariance matrix from a mesh.
It think it is something like gettinng the centroid of an object.
Those libraries are great is there an easy way to call them from
Python that you know ?

Ciao Bro
