[SciPy-user] matrix multipy ...

Perhaps it's simple, but...
Suppose I have 2 "vectors" (1xN matrix really)
n [27]: a = mat("1,2,3,4,5")
In [29]: b = mat("1,2,3")
If I whant the product, no problem.
But suppose I have a list of vectors (a proper matrix)
In [37]: aa = mat("1,2,3,4,5;6,7,8,9,0")
In [38]: bb = mat("1,2,3;4,5,6")
Can I avoid a loop and have the resulting "cube"?
In [40]: aa[0].T*bb[0]
Out[40]:
matrix([[ 1, 2, 3],
[ 2, 4, 6],
[ 3, 6, 9],
[ 4, 8, 12],
[ 5, 10, 15]])
I admit, I can't really understand array slicing power/limits!
Thank you,
Matteo Bertini
