[Cython] access to numpy functions?

Hello,

I have been using Pyrex/Cython for a couple years now, interfacing  
with the numpy ndarray objects.  I was wondering recently if there is  
direct access to some of the functions of numpy, like dot products,  
addition and subtraction, etc... without going through the python  
API?  If I have two objects in Cython/Pyrex, like:


c_numpy.ndarray x,y

and I want to do a dot product, or add the two arrays, is there  
access to the numpy C-version of this?  I know I could write my own  
for the dot product, but I'd rather not reinvent the wheel when  
possible.



			thanks,
