Using numpy 1.0 and trying the code below, I do not see the problem. import numpy from numpy import random m = random.randint(0,1000,(22973,1009)) v = random.randint(0,1000,(22973,)) fr = v[10001] for i in xrange(1009): m[:,i] = v if m[10001, i] != fr: print m[10001,i], fr Upgrading to numpy 1.0 should be easy enough and may fix your problem.
