	The way I understand it is that you need to have a matrix
multiplication (which is different to a 2D array multiplication). For
this you need matrixmultiply. An example from the manual:


>>> print a 

[[0 1 2]
[3 4 5]]
>>> print b 
[1 2 3]
>>> print a*b 
[[ 0 2 6]
[ 3 8 15]]
>>> print matrixmultiply(a,b) 
[ 8 26]

	Hope this helps
