This is simply Euclidean distance squared. Take the square root if you
need the simple Euclidean distance.

Hi
thanks a lot
I have also another problem ( :-) ). As I wrote in the previous email, I'm
using the RandomAccessSparseVector representation to store sparse vectors. I
need to sum some of them together, so I use the method plus but it seems
that it requires the same vector cardinality. I set the i
Cardinality should be set to whatever the logical dimension of the
vector is -- it shouldn't be arbitrary. It's not like an "initial
size" of a list. If your'e dealing with vectors that have a
potentially unbounded maximum dimension, use Integer.MAX_VALUE.
As the name suggests, the implementation
Dear Sean,
thanks a lot for the advices, everything is working perfectly!
Cheers
