Re: Computer Algebra Algorithms
I've been trying to follow this thread somewhat but there is many
more posts here then I want to toughly dissect. I don't really think
in the above posts enough motivation was given behind what you want to
do. If you want to learn CAS, learn lisp because that is what the open
source CAS are programmed in and a large part of the academic work in
AI uses lisp.
Actually, there are C++ programmed CAS, like my giac/xcas
www-fourier.ujf-grenoble.fr/~parisse/giac.html
They are more flexible for programmers because they are available
as C++ libraries, not only as a binary.
If you want to use C dynamically you are going to need some kind of
parser. The parser could be written in C or any other language. It
should return to you a tree structure representing the expression the
user typed at the command line. You could then perform some algebra on
it. In this case you may not care if you can overload the plus
operator. You could just call it as a C function pluss(a,b), since
everything would be done by your custom interpreter (would this really
be C?).
But the code will be more readable if you can write a+b in your source.
If you want to use C and you want to do something useful with CAS I
would suggest learning the external function interface of MAPLE. This
will allow you to Manipulate maple data structures in the Maple
workspace with C functions. I havn't got into it but perhaps you
could even use it to prevent the automatic simplification in Maple.
Apparently the best reference for this is the Maple advanced
programming guide. It is about 54 dollars.
You can do that with giac for free.
