hi
is this calculated distance really Euclidean distance? When i checked
wikipedia http://en.wikipedia.org/wiki/Euclidean_distance
it shows a calculation involving sum of squares of the differences of
elements.He

hello
while trying to write a function that processes some numpy arrays and
calculate euclidean distance ,i ended up with this code
(though i used numpy ,i believe my problem has more to do with python
coding style..so am posting it here)
...
# i am using these numpy.ndarrays to do the calculation
