Hi, my problem is the following and it can be split in 3 parts: 1) transform my object (expressions of various types) in a giac object 2) factorize the giac object 3) come back to my object.
I know how to do the problem 2): I used the type `gen' and the functions in the file sym2poly.{h,cc}.
About the problems 1) and 2) I did something in both the directions but I want ask you the best method to decompose a type gen. For example, if I have `g' of the type gen, where g = a + b + c + d, how can I consider the single summands? The same problem with a product of gen, a power of gen, ... How can I know if `g' is a sum of gen? Or a product of gen? I did not find these methods in the file gen.h. Is there documentation about these topics?
Thanks, bye Tatiana
