[Numpy-discussion] Distance Formula on an Array

Oops, one more thing. In reference to:
vec = array([[0,0,0],[0,1,0],[0,0,3]])
pos = array([0,4,0])
sqrt(((vec - pos)**2).sum(1)) -> array([ 4., 3., 5.])
Can I make "vec" an array of class instances? I tried:
class c:
def __init__(self):
self.position = [0,0,0]
vec = array([c(),c(),c()])
pos = array([0,4,0])
sqrt(((vec.position - pos)**2).sum(1))
Which doesn't work. I'm not familiar with class objects in arrays--how
should they be referenced?
Thanks again,
Ian
