I think you are right:
from numarray.ma import *
Rx = ones((2500,2500))
N = make_mask_none((2500,2500))
Rx = array(Rx,mask=N)
s = sum(sum(Rx))
print s ## this works, s is of type int, rather than maskedarray
(Stephen, I'm guessing you know how to pipe the error messages to a
file. If you know how to do this with DOS/windows, would you write me
privately and explain? Thanks for writing back so quickly, by the way.)
