I know a bit about SVD - I used it for a short period of time in Matlab, 
though I'm definately not an expert in it and I don't understand the 
whole theory with orthogality behind making it work so elegant as it 
is/does work out.

I'm making my first steps now with numpy, so there's a lot I don't know 
and haven't tried with numpy...
