[Matrix-SIG] Bug in matrixmultiply

[Mikkel Bollinger]

I have been using the NumPy-package and I believe I found a bug using
the function "matrixmultiply":

>>> c=asarray([[0,1,0],[0,0,0],[0,0,0]])  
>>> matrixmultiply(5,c)
array([[0, 0, 0],
       [5, 0, 0],
       [0, 0, 0]])     

and

>>> matrixmultiply(c,5)
array([[0, 5, 0],
       [0, 0, 0],
       [0, 0, 0]])

When multiplying with a constant, matrixmultiply should either raise an
error message or interpret "5" as 5*unitmatrix. However it should not
transpose the output matrix as is the case for matrixmultiply(5,c).
