Re: [GiNaC-list] retrieving wildcard replacements on C++

how would you retrieve the wildcard replacement in this case?

In this simple case I would simply divide a list element by x ;-). In general it is a bit more difficult, but you could use cout << "list of wild(1)-replacements:" << endl; for (int i=0; i<ocurrences.nops(); ++i) { lst repls; ocurrences.op(i).match(wild(1)*x, repls); cout << wild(1).subs(repls, subs_options::no_pattern) << endl; } Best wishes, Chris
