[Numpy-discussion] Different behaviour logical_and/and

[Aureli S. F. <Aur...@ip...>]

Hi all,

In the version of Numeric with MacPython2.2 the functions
"Numeric.logical_and" and "and" behave different, although up to the
on-line documentation they should behave the same:

>>> Numeric.logical_and(a,b)
array([0, 1, 0, 0, 0, 0, 1, 0, 0, 0])
>>> a and b
array([1, 1, 0, 1, 0, 0, 1, 1, 1, 0])

for arrays:

>>> a
array([0, 1, 0, 0, 1, 0, 1, 0, 0, 1])
>>> b
array([1, 1, 0, 1, 0, 0, 1, 1, 1, 0])

or am I misunderstood something...?

Regards,
Aureli
