As a mathematician I'd have to disagree with you there Alan. This model
already has an established notation:
Regardless of established notation, unless only mathematicians will be reading
the code, and only those intimately familiar with the equation, it makes much
more sense to use meaningful names. Because that way, when sending the code to
a mailing list full of non-mathematician programmers, they'll know exactly what
the variables are supposed to be for, so they wont have to look anything up on
wikipedia. After all, they've got a finite amount of volunteer time, and would
you prefer to get more advice about logic errors, or the guarenteed responses
about variable names?
I for one, prefer to get the most value from my question as possible. It shows
respect to the people I'm asking, and to everything else that they could
possibly be spending their time on, including answering other questions.
Respectfully-and-somewhat-tongue-in-cheekily,
Wayne
