Re: [GiNaC-list] comparing symbols

Hi,

try the code

cout << tree << "x = " << x << "\n";

then we can see what is going on.

x = lst @0x8a08c70, hash=0xc, flags=0x13, nops=2 0 (symbol) @0x8a3df40, serial=62607, hash=0x771ff4, flags=0x7, domain=0 1 (symbol) @0x8a2bde8, serial=62608, hash=0x771ff4, flags=0x7, domain=0

Maybe r_sum is called with something like symbol f1("0"); symbol f2("1"); r_sum(...,lst(f1,f2),...);

Wouldn't that eliminate functional dependence on the variables represented by f1 & f2, making the return value a function of "0" and "1". The end user could handle this by manually simplifying the output, but that wouldn't be optimal. Sincerely, Chris Bouchard
