Please forgive this slightly off-topic response.

Matt,

Are you aware of the Generalized Arithmetic Operators (genops) functions 
I developed for MATLAB?  They implement as MEX functions exactly this 
behavior.  For more info please see

We now return you to your regularly scheduled Python discussion.
