Re: factorization with GiNaC (update)

Hi Bernard, That looks promising, though it usually needs tons of small manual fixes to get it compiled. Before diving deeper into this: Could the replication of GiNaC header files not be avoided? That makes maintening your code a nightmare. You seem to be accessing class power's basis and exponent, hence declaring them public. (I hope you don't write them in reference counted objects anywhere.) For accessing, you could simply use the .op(0) and .op(1) method. I haven't understood yet what you do with expairseq but I am under the impression that this can be dealt with in the same way?
