"""Should this program take 4.3 seconds to run? I have a Linux PC with an AMD Athlon XP 2000+ chip (1.7Gh). I use Python 2.4.1 and numarray 1.2.3, both compliled from source."""
import time, numarray from numarray.numerictypes import *
nested = [] for i in range(8): inner = [] for j in range(8): inner.append(numarray.ones((256,256), Float64)) nested.append(inner) t = time.clock() arr = numarray.array(nested) print time.clock() - t
As mentioned, this has nothing to do with numarray, and everything to do with your inexplicable use of lists. Why don't you just write this as:
arr = numarray.ones((8, 8, 256, 256), Float64)
