[Tutor] First few eigenvectors of Numeric Array

[Stuart Murdock]

Hi

I have a 10000 by 10000 square Numeric array which I have obtained using 
Numeric python. I need to obtain the first 10 eigenvalues and
eigenvectors of this so I dont want to have to calculate all 
eigenvectors of the matrix. Is anyone aware of any pythonic packages which
can calculate, lets say, the 10 eigenvectors corresponding to the top 10 
eigenvalues of a Numeric array.

Thanks

Stuart
