Hi Scipy-Experts,
I've got a question concerning the summation of elements in an array. The
following small sample programm illustrates the problem:
_________________________________
from scipy.xplt import *
from RandomArray import *
nx,ny=100,10
def gen_lattice(nx,ny,c):
x=uniform(0.0,1.0,((nx,ny)))
return (x<c)
c=1
x=gen_lattice(nx,ny,c)
print sum(x)
print sum(ravel(x))
___________________________________
One would expect an output of ten 100s and a 1000 but instead of the 1000
it prints 232. Does anybody have a idea whats wrong?
To anticipate corresponding questions, normally I also want to vary c
between 0..1 ;-)
Thank you for your help!
Ciao by Philipp
