[~]$ cat test.py
from scipy import *
A = array([[1., 2.],
           [3., 4.]])
mA = matrix(A)

print 3*mA
print 3*A
print

mA*mA

print 3*mA
print 3*A
[~]$ python test.py
[[  3.   6.]
 [  9.  12.]]
[[  3.   6.]
 [  9.  12.]]

[[  3.   6.]
 [ 24.  34.]]
[[  3.   6.]
 [  9.  12.]]
----------------------------------------

I can't reproduce this at the prompt although it is showing up in the
unit tests I'm writing.
