Maybe most Omnimaga people don't know either or totally forgot? :O

Altough I agree a bit with Builderboy lol. Sometimes we buy a calc but end up using it more often for games than school.

I was going to write a CAS in C for the Nspire, but I couldn't find any input or output functions

That sucks you would definitely get better performance out of a CAS in C hell you wouldn't even need to write it you would just need to build a lisp interpreter and front end for Maxima.  And lisp is easy interpretation.

mhmm could you rephrase the second part of your sentence starting on the word "peephole", especially the "thous", "in-lining" and "inpack" parts? I am confused at what you mean

@Eeems: it's déjà-vu not deja'vou.

I actually don't fully understand how the library works yet but think there are better places to start like for example gutting parsing engine and rewriting it, refracting the way operators are handled and reducing excessive function calls. additionally I can make rather significant gains using matrix and list math for many where they are neglected for loops.  As I have said thus far I have only really done compiler like optimizations (and replacing the bubble sorts with something respectable) meaning I've reduced obviously redundant operations, remove excessive variables and copying, and operator strength reduction.





here's the promised working copy

I'm really embarrassed the library I posted doesn't work It just explodes anyway heres a working version of the library.
and good news I think I've figured out why the differentiation function is so slow and am working to fix it I think It will be a very small modification to the pf2tree function or the pf2tree function and it will be crazy much faster. I forget which at the moment. still happy day.  

sorry to hear

Where would I find this problem.
