If you don't have any specific questions then here's an example I made of using Cython in the Sage Notebook to perform fast matrix multiplication: (Note that I'm just re-implementing the naive algorithm using various stages of Python->Cython conversion.)

http://uw.sagenb.org/home/pub/19/

It's based on a talk made by one of the lead Cython developers. Also, the Cython documentation is excellent and most, if not all, of the language elements work naturally in the notebook environment.

I have another one demonstrating Sage/Pylab interfacing: http://uw.sagenb.org/home/pub/20/. This one is also based on a Cython talk.

Thanks very much for the notebook-oriented links. I'd issue thumbs up if not for my karma.

There are lots of examples if you search sagenb.org for "%cython": Here is the search

A particularly nice example is here

This question is extremely open ended and not very specific, so I'm not sure how to answer.

One point, is that you use %cython to create a notebook cell that is evaluated using Cython.

Do you have a more specific question about using Cython with the Sage notebook?

Thanks, I hadn't seen the %cython directive before. I didn't see cython in the language pull-down, and the docs I've found so far are command-line oriented. I was hoping for a small notebook example. I googled it, but didn't see what I was looking for.

A short example (notebook/cell-based) on the cython.org homepage would be great.
