Hi, I'm new to the list. I am having some difficulty finding the sum of
a masked array. I'm using numarray 1.0 installed on winXP with Python 2.3.4.
from numarray.ma import *
Rx = ones((2500,2500))
N = make_mask_none((2500,2500))
Rx = array(Rx,mask=N)
print average(Rx) ## works
print sum(Rx) ## gives an error message 16 lines long, the most recent
being a type error.
Is there something obvious I am doing wrong here?
