[Matrix-SIG] NaN

[Paul F. Dubois]

This worked for me on one machine.
C:\WINDOWS>python
Python 1.5.1 (#0, Apr 13 1998, 20:22:04) [MSC 32 bit (Intel)] on win32
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> from Numeric import *
>>> infinity=(array([1.0])/array([0.0]))[0]
>>> x=array([1.,2.,3.])
>>> y=array([1.,0.,1.])
>>> z=x/y
>>> print equal(z,infinity)
[0 1 0]
>>>
