Hi all. I have a rather odd question, and I don't know if this is something Axiom even will permit, but it would be useful to know, so...
I want to be able to teach Axiom how to use units. There are a number of surprisingly annoying features to handle based on my experience with Maxima, and one of the worst is the following: If I enter an expression, Axiom automatically formats it and orders it according to internal rules. See http://www.axiom-developer.org/zope/mathaction/[EMAIL PROTECTED] for an example of this. Normally, this is what one wants to do. What I'm not sure of is how to instruct Axiom to display things that are Units at the end of an expression, e.g. kg*m a*b*z ------ 2 s In Maxima it requires some rather alarming hackery with the display code to avoid the same default behavior Maxima exhibits. In one sense Axiom is an ideal place for certain types of unit operations, since I can presumably do things like assign both inches and meters the type Length, and assign simplification rules accordingly :-). but I don't know how to impliment the display logic above. Based on the Maxima experience, I'm guessing the infastructure might not be in place to support something like this, given it is rather non-standard in normal mathematical environments. Is there anybody who knows what the correct approach to this would be? Cheers, CY __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
